wbpB

Gene
wbpB
Protein
UDP-N-acetyl-2-amino-2-deoxy-D-glucuronate oxidase
Organism
Pseudomonas aeruginosa (strain ATCC 15692 / DSM 22644 / CIP 104116 / JCM 14847 / LMG 12228 / 1C / PRS 101 / PAO1)
Length
316 amino acids
Function
Plays a role in the biosynthesis of B-band O antigen for serotype O5. Catalyzes the NAD-dependent oxidation of UDP-N-acetylglucosaminuronic acid (UDP-D-GlcNAcA) to UDP-2-acetamido-2-deoxy-3-oxo-D-glucuronic acid (UDP-3-oxo-D-GlcNAcA). Cannot use UDP-GlcNAc or UDP-GalNAc as the nucleotide sugar substrate, and can use only poorly UDP-D-glucuronic acid (UDP-GlcA). Undergoes an NAD(+) recycling mechanism using 2-oxoglutarate as an oxidant.
Similarity
Belongs to the Gfo/Idh/MocA family.
Mass
35.718 kDa
