A	alpha-1,3-mannosyl-glycoprotein 2-beta-N-acetylglucosaminyltransferase M-CSA #770	N-acetylglucosaminyltransferase I (GnT I) is an inverting glycosyl transferase from Oryctolagus cuniculus catalyses the attachment of N-acetyl glucosamine (GlcNAc) onto an oligomannose core, from UPD-N-acetyl glucosamine. It plays a critical role in mammalian development, involved in the transformation of oligomannose attached structures to complex N-glycans.
