Term ID

GO:0017122

Synonyms

• O-GlcNAc transferase complex
• UDP-N-acetylglucosamine-peptide N-acetylglucosaminyltransferase

Definition

A protein complex capable of protein N-acetylglucosaminyltransferase activity, the addition of nucleotide-activated sugars onto the polypeptide according to reaction: UDP-N-acetyl-D-glucosamine + protein = UDP + 4-N-(N-acetyl-D-glucosaminyl)-protein. The complex has different compositions in different species: In mammals it is often a homotrimer, in bacteria a heterotetramer of 2 different subunits. 15247246
