Structural highlights
FunctionPMT4_YEAST Protein O-mannosyltransferase involved in O-glycosylation which is essential for cell wall rigidity. Forms a homodimeric complex to transfer mannose from Dol-P-mannose to Ser or Thr residues on proteins. Specifically acts on secretory proteins with an ER-luminally oriented Ser/Thr-rich region flanked by a membrane anchor such as FUS1, AXL2, GAS1, KEX2, MID2, WSC1, WSC2, OPY2, PRM5, RAX2, or YNL176.[1] [2] [3] [4] References
