3-hydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione monooxygenase.
based on mapping to UniProt P9WJA1
3-hydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione + FMNH(2) + O(2) = 3,4-dihydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione + FMN + H(2)O.
-!- This bacterial enzyme participates in the degradation of several steroids, including cholesterol and testosterone. -!- It can use either FADH or FMNH(2) as flavin cofactor. -!- The enzyme forms a two-component system with a reductase (HsaB) that utilizes NADH to reduce the flavin, which is then transferred to the oxygenase subunit.
