Comment |
A pyridoxal 5'-phosphate protein. This enzyme participates in the biosynthetic pathway for UDP-alpha-D-ManNAc3NAcA (UDP-2,3-diacetamido-2,3-dideoxy-alpha-D-mannuronic acid), an important precursor of B-band lipopolysaccharide. The enzymes from Pseudomonas aeruginosa serotype O5 and Thermus thermophilus form a complex with the previous enzyme in the pathway, EC 1.1.1.335 (UDP-N-acetyl-2-amino-2-deoxyglucuronate oxidase).
