Species: Pseudomonas aeruginosa
The ability of Pseudomonas aeruginosa to decompose urate was not constitutive, and developed about two hours after exposure to urate, suggesting that the enzyme is inducible [Bachrach57]. 3 atoms of oxygen were taken up for every mole of urate which disappeared.
In a later experiment the activity of factor-independent urate hydroxylase from Pseudomonas aeruginosa was measured using cell extracts, by following the disappearance of urate. Specific activity was 0.065 μmol/min/mg protein [Bongaerts77].
