General Information

Term

dol-P-Man:Man(2)GlcN-acyl-PI alpha-1,2-mannosyltransferase activity

ID (Ontology)

GO:0120564 (Gene Ontology)

Definition

Catalysis of the transfer of an alpha-D-mannosyl residue from dolichol-P-mannose to Man(2)-GlcN-acyl-PI, forming an alpha-(1->2)-D-mannosyl-D-mannose linkage. This transfers the third mannose to the GPI precursor.[ PubMed:8861954 ]

Also Known As
