Crystal structure of the WlbA (WbpB) dehydrogenase from Pseudomonas aeruginosa in complex with NAD at 1.5 angstrom resolution
Template:ABSTRACT PUBMED 20690587
Function
[P72133_PSEAE] 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). Can not 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.[1] [2] [3] [4]
About this Structure
3oa2 is a 4 chain structure with sequence from Pseudomonas aeruginosa. Full crystallographic information is available from OCA.
