【 摘 要 】

Both soluble and microsomal fractions of Fusarium oxysporum contain cytochrome P-450(P-450). We report here that the P-450 in the soluble fraction was induced only when nitrate or nitrite was added to the growth medium, whereas the microsomal P-450 was synthesized regardless of the medium compositions. The reduced-CO complex of the soluble P-450 exhibited an absorption spectrum that is different from that of the microsomal counterpart. These results indicate that the soluble P-450 is distinct from the microsomal species and suggest a novel function for the former P-450.
