A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 3.2.1.169

Accepted Name
Protein O-GlcNAcase.
Alternative Name(s)
Glycoside hydrolase O-GlcNAcase.
O-GlcNAc hydrolase.
O-GlcNAcase.
OGA.
Reaction catalysed
  • [Protein]-3-O-(N-acetyl-beta-D-glucosaminyl)-L-serine + H(2)O <=> [protein]-L-serine + N-acetyl-D-glucosamine
  • [Protein]-3-O-(N-acetyl-beta-D-glucosaminyl)-L-threonine + H(2)O <=> [protein]-L-threonine + 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.
