IUBMB Enzyme Nomenclature


Accepted name: diglucosylglycerate octanoyltransferase

Reaction: octanoyl-CoA + 2-O-[α-D-glucopyranosyl-(1→6)-α-D-glucopyranosyl]-D-glycerate = 2-O-[6-O-octanoyl-α-D-glucopyranosyl-(1→6)-α-D-glucopyranosyl]-D-glycerate. + CoA

Other name(s): octT (gene name); DGG octanoyltransferase

Systematic name: octanoyl-CoA:2-O-[α-D-glucopyranosyl-(1→6)-α-D-glucopyranosyl]-D-glycerate octanoyltransferase

Comments: The enzyme, characterized from mycobacteria, is involved in the biosynthesis of methylglucose lipopolysaccharide (MGLP). The enzyme can also act on 2-O-(α-D-glucopyranosyl)-D-glycerate, but with lower activity.
