EC	2.4.1.374
Accepted name:	β-1,2-mannooligosaccharide synthase
Reaction:	GDP-α-D-mannose + [(1→2)-β-D-mannosyl]n = GDP + [(1→2)-β-D-mannosyl]n+1
Other name(s):	MTP1 (gene name); MTP2 (gene name)
Systematic name:	GDP-α-D-mannose:(1→2)-β-D-mannan mannosyltransferase (configuration-inverting)
Comments:	The enzyme, characterized from Leishmania parasites, is involved in synthesis of mannogen, a β-(1→2)-mannan oligosaccharide used by the organisms as a carbohydrate reserve.
