O-linked N-acetylglucosamine hydrolase (OGA)

Target
OGA
Molecular classification
Enzyme, Glycoside Hydrolase
01

Overview

O-linked N-acetylglucosamine hydrolase (OGA) is an enzyme responsible for removing the monosaccharide modification *O*-linked β-N-acetylglucosamine (*O*-GlcNAc) from serine and threonine residues of nuclear, cytoplasmic, and mitochondrial proteins. This process is a key part of the dynamic post-translational modification cycle called *O*-GlcNAcylation. The balance between OGA and OGT (O-GlcNAc transferase) is crucial for normal cell function, and dysregulation has been linked to various diseases.
