ENTRY       EC 2.4.1.48
NAME        Heteroglycan alpha-mannosyltransferase
CLASS       Transferases
            Glycosyltransferases
            Hexosyltransferases
SYSNAME     GDPmannose:heteroglycan 2-(or 3-)-alpha-D-mannosyltransferase
REACTION    GDPmannose + Heteroglycan = GDP + 1,2-alpha-D-Mannosyl
            $heteroglycan or 1,3-alpha-D-Mannosylheteroglycan
SUBSTRATE   GDPmannose
            Heteroglycan
PRODUCT     GDP
            1,2-alpha-D-Mannosylheteroglycan
            1,3-alpha-D-Mannosylheteroglycan
COMMENT     The acceptor is a heteroglycan primer containing mannose,
            galactose and xylose.  1,2- and 1,3-mannosyl bonds are formed.
