Abstract excerpt
Cytochrome P450scc (P450 11A1) catalyzes the conversion of cholesterol to pregnenolone, the first step in overall steroid hormone biosynthesis in steroidogenic tissues. On the basis of alignment with structurally characterized cytochromes P450 (P450s), we have identified the putative F-G loop of P450 11A1 and mutated amino acid residues in this region. Wild type and mutant P450s 11A1 were expressed in E. coli and...
