ID   2.5.1.132
DE   3-deoxy-D-glycero-D-galacto-nononate 9-phosphate synthase.
AN   2-keto-3-deoxy-D-glycero-D-galacto-9-phosphonononic acid synthase.
AN   KDN 9-P synthase.
CA   D-mannose 6-phosphate + H2O + phosphoenolpyruvate = 3-deoxy-D-glycero-
CA   beta-D-galacto-non-2-ulopyranosonate 9-phosphate + phosphate.
CC   -!- The enzyme participates in the biosynthesis of the sialic acid
CC       3-deoxy-D-glycero-D-galacto-nononate (KDN).
CC   -!- The human sialic acid synthase (EC 2.5.1.57) is also able to catalyze
CC       the reaction.
CC   -!- KDN is abundant in extracellular glycoconjugates of lower vertebrates
CC       such as fish and amphibians, but is also found in the capsular
CC       polysaccharides of bacteria that belong to the Bacteroides genus.
