ENZYME entry: EC 3.2.1.169

Accepted Name
protein O-GlcNAcase
Alternative Name(s)
glycoside hydrolase O-GlcNAcase
OGA
O-GlcNAcase
O-GlcNAc hydrolase
Reaction catalysed
  • 3-O-(N-acetyl-beta-D-glucosaminyl)-L-seryl-[protein] + H2O = L-seryl-[protein] + N-acetyl-D-glucosamine
  • 3-O-(N-acetyl-beta-D-glucosaminyl)-L-threonyl-[protein] + H2O = L-threonyl-[protein] + N-acetyl-D-glucosamine
Comment(s)
  • Within higher eukaryotes post-translational modification of protein serines/threonines with N-acetylglucosamine (O-GlcNAc) is dynamic, inducible and abundant, regulating many cellular processes by interfering with protein phosphorylation.
  • EC 2.4.1.155 transfers GlcNAc onto substrate proteins and EC 3.2.1.169 cleaves GlcNAc from the modified proteins.
