Joiner CM, Hammel FA, Janetzko J, Walker S. Protein Substrates Engage the Lumen of O-GlcNAc Transferase's Tetratricopeptide Repeat Domain in Different Ways. Biochemistry 2021 60(11) 33709700
Abstract:
Glycosylation of nuclear and cytoplasmic proteins is an essential post-translational modification in mammals. O-GlcNAc transferase (OGT), the sole enzyme responsible for this modification, glycosylates more than 1000 unique nuclear and cytoplasmic substrates. How OGT selects its substrates is a fundamental question that must be answered to understand OGT's unusual biology. OGT contains a long tetratricopeptide repeat (TPR) domain that has been implicated in substrate selection, but there is almost no information about how changes to this domain affect glycosylation of individual substrates. By profiling O-GlcNAc in cell extracts and probing glycosylation of purified substrates, we show here that ladders of asparagines and aspartates that extend the full length of OGT's TPR lumen control substrate glycosylation. Different substrates are sensitive to changes in different regions of OGT's TPR lumen. We also found that substrates with glycosylation sites close to the C-terminus bypass lumenal binding. Our findings demonstrate that substrates can engage OGT in a variety of different ways for glycosylation.

A Direct Fluorescent Activity Assay for Glycosyltransferases Enables Convenient High-Throughput Screening: Application to O-GlcNAc Transferase. Angewandte Chemie (International ed. in English) 2020 59(24) 32092778
Abstract:
Glycosyltransferases carry out important cellular functions in species ranging from bacteria to humans. Despite their essential roles in biology, simple and robust activity assays that can be easily applied to high-throughput screening for inhibitors of these enzymes have been challenging to develop. Herein, we report a bead-based strategy to measure the group-transfer activity of glycosyltransferases sensitively using simple fluorescence measurements, without the need for coupled enzymes or secondary reactions. We validate the performance and accuracy of the assay using O-GlcNAc transferase (OGT) as a model system through detailed Michaelis-Menten kinetic analysis of various substrates and inhibitors. Optimization of this assay and application to high-throughput screening enabled screening for inhibitors of OGT, leading to a novel inhibitory scaffold. We believe this assay will prove valuable not only for the study of OGT, but also more widely as a general approach for the screening of glycosyltransferases and other group-transfer enzymes.

Abstract:
O-Linked β-N-acetylglucosamine (O-GlcNAc) is a monosaccharide that plays an essential role in cellular signaling throughout the nucleocytoplasmic proteome of eukaryotic cells. Strategies for selectively increasing O-GlcNAc levels on a target protein in cells would accelerate studies of this essential modification. Here, we report a generalizable strategy for introducing O-GlcNAc into selected target proteins in cells using a nanobody as a proximity-directing agent fused to O-GlcNAc transferase (OGT). Fusion of a nanobody that recognizes GFP (nGFP) or a nanobody that recognizes the four-amino acid sequence EPEA (nEPEA) to OGT yielded nanobody-OGT constructs that selectively delivered O-GlcNAc to a series of tagged target proteins (e.g., JunB, cJun, and Nup62). Truncation of the tetratricopeptide repeat domain as in OGT(4) increased selectivity for the target protein through the nanobody by reducing global elevation of O-GlcNAc levels in the cell. Quantitative chemical proteomics confirmed the increase in O-GlcNAc to the target protein by nanobody-OGT(4). Glycoproteomics revealed that nanobody-OGT(4) or full-length OGT produced a similar glycosite profile on the target protein JunB and Nup62. Finally, we demonstrate the ability to selectively target endogenous α-synuclein for O-GlcNAcylation in HEK293T cells. These first proximity-directed OGT constructs provide a flexible strategy for targeting additional proteins and a template for further engineering of OGT and the O-GlcNAc proteome in the future. The use of a nanobody to redirect OGT substrate selection for glycosylation of desired proteins in cells may further constitute a generalizable strategy for controlling a broader array of post-translational modifications in cells.

Escobar EE, King DT, Serrano-Negrón JE, Alteen MG, Vocadlo DJ, Brodbelt JS. Precision Mapping of O-Linked N-Acetylglucosamine Sites in Proteins Using Ultraviolet Photodissociation Mass Spectrometry. Journal of the American Chemical Society 2020 142(26) 32510947
Abstract:
Despite its central importance as a regulator of cellular physiology, identification and precise mapping of O-linked N-acetylglucosamine (O-GlcNAc) post-translational modification (PTM) sites in proteins by mass spectrometry (MS) remains a considerable technical challenge. This is due in part to cleavage of the glycosidic bond occurring prior to the peptide backbone during collisionally activated dissociation (CAD), which leads to generation of characteristic oxocarbenium ions and impairs glycosite localization. Herein, we leverage CAD-induced oxocarbenium ion generation to trigger ultraviolet photodissociation (UVPD), an alternate high-energy deposition method that offers extensive fragmentation of peptides while leaving the glycosite intact. Upon activation using UV laser pulses, efficient photodissociation of glycopeptides is achieved with production of multiple sequence ions that enable robust and precise localization of O-GlcNAc sites. Application of this method to tryptic peptides originating from O-GlcNAcylated proteins TAB1 and Polyhomeotic confirmed previously reported O-GlcNAc sites in TAB1 (S395 and S396) and uncovered new sites within both proteins. We expect this strategy will complement existing MS/MS methods and be broadly useful for mapping O-GlcNAcylated residues of both proteins and proteomes.

Xu S, Sun F, Wu R. A Chemoenzymatic Method Based on Easily Accessible Enzymes for Profiling Protein O-GlcNAcylation. Analytical chemistry 2020 92(14) 32574038
Abstract:
O-GlcNAcylation has gradually been recognized as a critically important protein post-translational modification in mammalian cells. Besides regulation of gene expression, its crosstalk with protein phosphorylation is vital for cell signaling. Despite its importance, comprehensive analysis of O-GlcNAcylation is extraordinarily challenging due to the low abundances of many O-GlcNAcylated proteins and the complexity of biological samples. Here, we developed a novel chemoenzymatic method based on a wild-type galactosyltransferase and uridine diphosphate galactose (UDP-Gal) for global and site-specific analysis of protein O-GlcNAcylation. This method integrates enzymatic reactions and hydrazide chemistry to enrich O-GlcNAcylated peptides. All reagents used are more easily accessible and cost-effective as compared to the engineered enzyme and click chemistry reagents. Biological triplicate experiments were performed to validate the effectiveness and the reproducibility of this method, and the results are comparable with the previous chemoenzymatic method using the engineered enzyme and click chemistry. Moreover, because of the promiscuity of the galactosyltransferase, 18 unique O-glucosylated peptides were identified on the EGF domain from nine proteins. Considering that effective and approachable methods are critical to advance glycoscience research, the current method without any sample restrictions can be widely applied for global analysis of protein O-GlcNAcylation in different samples.

Abstract:
O-GlcNAcylation is an abundant and dynamic protein posttranslational modification (PTM), with crucial roles in metazoans. Studies of this modification are hampered by the lack of convenient methods for detecting native O-GlcNAcylation. Here, we describe a novel gel-based approach, Separation of O-GlcNAcylated Proteins by Polyacrylamide Gel Electrophoresis (SOPAGE), which enables detection of O-GlcNAc levels and dynamics.

Abstract:
O-GlcNAc modification plays critical roles in regulating the stress response program and cellular homeostasis. However, systematic and multi-omics studies on the O-GlcNAc regulated mechanism have been limited. Here, comprehensive data are obtained by a chemical reporter-based method to survey O-GlcNAc function in human breast cancer cells stimulated with the genotoxic agent adriamycin. We identify 875 genotoxic stress-induced O-GlcNAc chromatin-associated proteins (OCPs), including 88 O-GlcNAc chromatin-associated transcription factors and cofactors (OCTFs), subsequently map their genomic loci, and construct a comprehensive transcriptional reprogramming network. Notably, genotoxicity-induced O-GlcNAc enhances the genome-wide interactions of OCPs with chromatin. The dynamic binding switch of hundreds of OCPs from enhancers to promoters is identified as a crucial feature in the specific transcriptional activation of genes involved in the adaptation of cancer cells to genotoxic stress. The OCTF nuclear factor erythroid 2-related factor-1 (NRF1) is found to be a key response regulator in O-GlcNAc-modulated cellular homeostasis. These results provide a valuable clue suggesting that OCPs act as stress sensors by regulating the expression of various genes to protect cancer cells from genotoxic stress.

Li J, Li Z, Duan X, Qin K, Dang L, Sun S, Cai L, Hsieh-Wilson LC, Wu L, Yi W. An Isotope-Coded Photocleavable Probe for Quantitative Profiling of Protein O-GlcNAcylation. ACS chemical biology 2019 14(1) 30620550
Abstract:
O-linked N-acetylglucosamine ( O-GlcNAc) is a ubiquitous post-translational modification of proteins and is essential for cell function. Quantifying the dynamics of O-GlcNAcylation in a proteome-wide level is critical for uncovering cellular mechanisms and functional roles of O-GlcNAcylation in cells. Here, we develop an isotope-coded photocleavable probe for profiling protein O-GlcNAcylation dynamics using quantitative mass spectrometry-based proteomics. This probe enables selective tagging and isotopic labeling of O-GlcNAcylated proteins in one step from complex cellular mixtures. We demonstrate the application of the probe to quantitatively profile O-GlcNAcylation sites in 293T cells upon chemical induction of O-GlcNAc levels. We further applied the probe to quantitatively analyze the stoichiometry of O-GlcNAcylation between sorafenib-sensitive and sorafenib-resistant liver cancer cells, which lays the foundation for mechanistic investigation of O-GlcNAcylation in regulating cancer chemoresistance. Thus, this probe provides a powerful tool to profile O-GlcNAcylation dynamics in cells.

Joiner CM, Levine ZG, Aonbangkhen C, Woo CM, Walker S. Aspartate Residues Far from the Active Site Drive O-GlcNAc Transferase Substrate Selection. Journal of the American Chemical Society 2019 141(33) 31373491
Abstract:
O-GlcNAc is an abundant post-translational modification found on nuclear and cytoplasmic proteins in all metazoans. This modification regulates a wide variety of cellular processes, and elevated O-GlcNAc levels have been implicated in cancer progression. A single essential enzyme, O-GlcNAc transferase (OGT), is responsible for all nucleocytoplasmic O-GlcNAcylation. Understanding how this enzyme chooses its substrates is critical for understanding, and potentially manipulating, its functions. Here we use protein microarray technology and proteome-wide glycosylation profiling to show that conserved aspartate residues in the tetratricopeptide repeat (TPR) lumen of OGT drive substrate selection. Changing these residues to alanines alters substrate selectivity and unexpectedly increases rates of protein glycosylation. Our findings support a model where sites of glycosylation for many OGT substrates are determined by TPR domain contacts to substrate side chains five to fifteen residues C-terminal to the glycosite. In addition to guiding design of inhibitors that target OGT's TPR domain, this information will inform efforts to engineer substrates to explore biological functions.
