ID 3.2.1.169 DE protein O-GlcNAcase. AN glycoside hydrolase O-GlcNAcase. AN OGA. AN O-GlcNAcase. AN O-GlcNAc hydrolase. CA (1) 3-O-(N-acetyl-beta-D-glucosaminyl)-L-seryl-[protein] + H2O = L-seryl- CA [protein] + N-acetyl-D-glucosamine. CA (2) 3-O-(N-acetyl-beta-D-glucosaminyl)-L-threonyl-[protein] + H2O = CA L-threonyl-[protein] + N-acetyl-D-glucosamine. CC -!- Within higher eukaryotes post-translational modification of protein CC serines/threonines with N-acetylglucosamine (O-GlcNAc) is dynamic, CC inducible and abundant, regulating many cellular processes by CC interfering with protein phosphorylation. CC -!- EC 2.4.1.155 transfers GlcNAc onto substrate proteins and CC EC 3.2.1.169 cleaves GlcNAc from the modified proteins.
