Reaction: GDP-mannose + heteroglycan = GDP + 2(or 3)-α-D-mannosyl-heteroglycan
Other name(s): GDP mannose α-mannosyltransferase; guanosine diphosphomannose-heteroglycan α-mannosyltransferase
Systematic name: GDP-mannose:heteroglycan 2-(or 3-)-α-D-mannosyltransferase
Comments: The acceptor is a heteroglycan primer containing mannose, galactose and xylose. 1,2- and 1,3-mannosyl bonds are formed.
