based on mapping to UniProt Q47592
ATP + alpha-D-Man-(1->2)-alpha-D-Man-(1->2)-(alpha-D-Man-(1->3)-alpha-D- Man-(1->3)-alpha-D-Man-(1->2)-alpha-D-Man-(1->2))(n)-alpha-D-Man-(1->3)- alpha-D-Man-(1->3)-alpha-D-Man-(1->3)-alpha-D-GlcNAc-diphospho- ditrans,octacis-undecaprenol = ADP + 3-O-phospho-alpha-D-Man-(1->2)- alpha-D-Man-(1->2)-(alpha-D-Man-(1->3)-alpha-D-Man-(1->3)-alpha-D-Man- (1->2)-alpha-D-Man-(1->2))(n)-alpha-D-Man-(1->3)-alpha-D-Man-(1->3)- alpha-D-Man-(1->3)-alpha-D-GlcNAc-diphospho-ditrans,octacis-undecaprenol.
-!- The enzyme is involved in the biosynthesis of the polymannose O-polysaccharide in the outer leaflet of the membrane of Escherichia coli serotype O9a. -!- O-polysaccharide structures vary extensively because of differences in the number and type of sugars in the repeat unit. -!- The dual kinase/methylase WbdD also catalyzes the methylation of 3-phospho-alpha-D-Man-(1->2)-alpha-D-Man-(1->2)-(alpha-D-Man-(1->3)- alpha-D-Man-(1->3)-alpha-D-Man-(1->2)-alpha-D-Man-(1->2))(n)-alpha-D- Man-(1->3)-alpha-D-Man-(1->3)-alpha-D-Man-(1->3)-alpha-D-GlcNAc- diphospho-ditrans,octacis-undecaprenol (Cf. EC 2.1.1.294).
