Comments [?]

Function Required for polymorphic O-glycosylation of the serine-rich repeat protein in this bacteria. Catalyzes the first step in glycosylation by transferring N-acetylglucosamine from UDP-GlcNAc to serine residues in the substrate protein. Part of the accessory SecA2/SecY2 system specifically required to export serine-rich repeat cell wall proteins usually encoded upstream in the same operon.
Catalytic activity RHEA:59872: L-seryl-[protein] + UDP-N-acetyl-alpha-D-glucosamine = 3-O-[N-acetyl-alpha-D-glucosaminyl]-L-seryl-[protein] + H(+) + UDP
Pathway Protein modification; protein glycosylation.
Subunit Forms a heterotetramer with 2 subunits each of GtfA and GtfB. Part of the accessory SecA2/SecY2 protein translocation apparatus.
Subcellular location Cytoplasm. Cell membrane; Peripheral membrane protein. Note=Cell membrane association requires GtfB.
Similarity Belongs to the glycosyltransferase group 1 family. Glycosyltransferase 4 subfamily.
