SYSTEMATIC NAME

IUBMB Comments

urate,NADH:oxygen oxidoreductase (5-hydroxyisourate-forming)

A flavoprotein. The reaction is part of the purine catabolic pathway in the bacterium Klebsiella pneumoniae. The enzyme is different from EC 1.7.3.3, factor-independent urate hydroxylase, found in most plants, which produces hydrogen peroxide. The product of the enzyme is a substrate for EC 3.5.2.17, hydroxyisourate hydrolase.
