3-Deoxy-D-manno-octulosonate 8-phosphate (KDO8P) synthase catalyses the condensation reaction between phosphoenolpyruvate and D-arabinose 5-phosphate (D-A5P) in a key step in lipopolysaccharide biosynthesis in Gram-negative bacteria. The KDO8P synthase from Neisseria meningitidis was cloned into Escherichia coli, overexpressed and purified. A variety of D-A5P stereoisomers were tested as substrates
