摘要：

The interactions of the individually expressed haem- and flavin-containing domains of cytochrome P-450 BM3 have been analysed by enzymological and spectroscopic techniques. Electron transfer between the isolated domains occurs at a much lower rate than that occurring in the intact flavocytochrome. CD spectroscopic studies indicate that the linkage of the domains in intact P-450 BM3 creates haem and amino acid environments suitable for efficient electron transfer from its flavin domain.
