1.14.13.113
FAD-dependent urate hydroxylase.
based on mapping to UniProt A6T923
Urate + NADH + O(2) = 5-hydroxyisourate + NAD(+) + H(2)O.
-!- The reaction is part of the purine catabolic pathway in the bacterium Klebsiella pneumoniae. -!- The enzyme is different from EC 1.7.3.3, found in most plants, which produces hydrogen peroxide. -!- The product of the enzyme is a substrate for EC 3.5.2.17.
