title: Evidence for and characterization of cytochrome P-450 in Neurospora crassa.
abstract: Cytochrome P-450 was detected in microsomes and presumably in cytosol of Neurospora crassa, and was found to be inducible by progesterone. In the microsomal fraction cytochrome b5 and NADPH-cytochrome c reductase activities were measurable, too. Cytochrome P-450 of Neurospora crassa is inhibited by SKF-525 A and by inhibitors of ergosterol biosynthesis. After induction of cytochrome P-450 with progesterone 11 alpha-hydroxyprogesterone as one metabolite of progesterone was detected in the culture media as well as in the mycelia. After 42 hours about 70% of progesterone were metabolized.
