Comment
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
2.4.1.255 (protein O-GlcNAc transferase) transfers GlcNAc onto substrate proteins and EC
3.2.1.169 (protein O-GlcNAcase) cleaves GlcNAc from the modified proteins.
History
EC 3.2.1.169 created 2011
Orthology
K15719 protein O-GlcNAcase / histone acetyltransferase
