Identification
Name:glucosyl-(heptosyl)2-Kdo2-lipid A
DescriptionGlucosyl-(heptosyl)2-Kdo2-lipid A is an intermediate in lipid A-core biosynthesis pathway in E.coli. It is a substrate for the enzyme lipopolysaccharide core heptose (I) kinase which catalyzes the reaction glucosyl-(heptosyl)2-Kdo2-lipid A + ATP -> glucosyl-(heptosyl)2-Kdo2-lipid A-phosphate + ADP + H+. It is also a product for enzyme lipopolysaccharide glucosyltransferase I which catalyzes reaction UDP-alpha-D-glucose + (heptosyl)2-Kdo2-lipid A -> glucosyl-(heptosyl)2-Kdo2-lipid A + UDP + H+ (BioCyc compound: CPD0-932).
