5.B.7.1.1
Probable sulfoxide reductase heme-binding flavocytochrome subunit, YedZ of 211 aas and 6 TMSs (von Rozycki et al. 2004).  Is involved in electron transfer between its heme and the molybdenum cofactor of the reductase catalytic subunit YedY (P76342) and serves as the anchor for YedY (Brokx et al. 2005).  YedY can catalyze the reduction of a variety of substrates like dimethyl sulfoxide, trimethylamine N-oxide, phenylmethyl sulfoxide and L-methionine sulfoxide (Loschi et al. 2004).
