EC 3.1.3.103     
Accepted name: 3-deoxy-D-glycero-D-galacto-nonulopyranosonate 9-phosphatase
Reaction: 3-deoxy-D-glycero-D-galacto-non-2-ulopyranosonate 9-phosphate + H2O = 3-deoxy-D-glycero-D-galacto-non-2-ulopyranosonate + phosphate
Other name(s): 3-deoxy-D-glycero-D-galacto-non-2-ulopyranosonate-9-phosphate phosphatase
Systematic name: 3-deoxy-D-glycero-D-galacto-non-2-ulopyranosonate 9-phosphohydrolase
Comments: The enzyme, characterized from the bacterium Bacteroides thetaiotaomicron, is part of the biosynthesis pathway of the sialic acid 3-deoxy-D-glycero-D-galacto-non-2-ulopyranosonate (Kdn). Kdn is abundant in extracellular glycoconjugates of lower vertebrates such as fish and amphibians, but is also found in the capsular polysaccharides of bacteria that belong to the Bacteroides genus.
