Protein

Xanthine dehydrogenase FAD-binding subunit

Gene
xdhB, Z4206, ECs3740
Organism
Escherichia coli O157:H7
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Presumed to be a dehydrogenase, but possibly an oxidase. Participates in limited purine salvage (requires aspartate) but does not support aerobic growth on purines as the sole carbon source (purine catabolism) By similarity.

Catalytic activityi

Xanthine + NAD+ + H2O = urate + NADH.
Hypoxanthine + NAD+ + H2O = xanthine + NADH.

Cofactori

FAD By similarity.
