DE   3-hydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione monooxygenase.
CA   3-hydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione + FMNH2 + O2 =
CA   3,4-dihydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione + FMN + H(+)
CA   + H2O.
CC   -!- This bacterial enzyme participates in the degradation of several
CC       steroids, including cholesterol and testosterone.
CC   -!- It can use either FADH or FMNH2 as flavin cofactor.
CC   -!- The enzyme forms a two-component system with a reductase (HsaB) that
CC       utilizes NADH to reduce the flavin, which is then transferred to the
CC       oxygenase subunit.
