Fatty acid synthase inhibits the O-GlcNAcase during oxidative stress [PDF]
The dynamic post-translational modification O-linked β-N-acetylglucosamine (O-GlcNAc) regulates thousands of nuclear, cytoplasmic, and mitochondrial proteins. Cellular stress, including oxidative stress, results in increased O-GlcNAcylation of numerous proteins, and this increase is thought to promote cell survival. The mechanisms by which the O-GlcNAc

Adding a single O-GlcNAc moiety to a Ser/Thr molecule of a protein by O-GlcNAc transferase and transiently removing it by O-GlcNAcase is referred to as O-GlcNAc cycling (or O-GlcNAcylation).

O-GlcNAcase (OGA) is the only enzyme responsible for removing N-acetyl glucosamine (GlcNAc) attached to serine and threonine residues on proteins. This enzyme plays a key role in O-GlcNAc metabolism.

Enzymatic characterization of O-GlcNAcase isoforms using a fluorogenic GlcNAc substrate [PDF]
A highly sensitive fluorogenic hexosaminidase substrate, fluorescein di(N-acetyl-beta-D-glucosaminide) (FDGlcNAc), was prepared essentially as described previously [Chem. Pharm. Bull. 1993, 41, 314] with some modifications. The fluorescent analog is a substrate for a number of hexosaminidases but here we have focused on the cytoplasmic O-GlcNAcase ...

O-GlcNAc as an Integrator of Signaling Pathways
O-GlcNAcylation is an important posttranslational modification governed by a single pair of enzymes–O-GlcNAc transferase (OGT) and O-GlcNAcase (OGA). These two enzymes mediate the dynamic cycling of O-GlcNAcylation on a wide variety of cytosolic, nuclear

O-GlcNAcylation in Chronic Lymphocytic Leukemia and Other Blood Cancers
In the past decade, aberrant O-GlcNAcylation has emerged as a new hallmark of cancer. O-GlcNAcylation is a post-translational modification that results when the amino-sugar β-D-N-acetylglucosamine (GlcNAc) is made in the hexosamine biosynthesis pathway ...

O-GlcNAc modification blocks the aggregation and toxicity of the protein α-synuclein associated with Parkinson's disease. [PDF]
Several aggregation-prone proteins associated with neurodegenerative diseases can be modified by O-linked N-acetyl-glucosamine (O-GlcNAc) in vivo. One of these proteins, α-synuclein, is a toxic aggregating protein associated with synucleinopathies ...

Recognition of diazirine-modified O-GlcNAc by human O-GlcNAcase. [PDF]
Mutagenesis of O-GlcNAcase offers insight into its substrate binding pocket and yields a mutant enzyme capable of hydrolyzing photocrosslinking O-GlcNAc.

Cell-Penetrant, Nanomolar O-GlcNAcase Inhibitors Selective against Lysosomal Hexosaminidases
Posttranslational modification of metazoan nucleocytoplasmic proteins with N-acetylglucosamine (O-GlcNAc) is essential, dynamic, and inducible and can compete with protein phosphorylation in signal transduction. Inhibitors of O-GlcNAcase, the enzyme removing O-GlcNAc, are useful tools for studying the role of O-GlcNAc in a range of cellular processes ...
