We have developed a simple procedure for analyzing the reaction intermediates and product of the cholesterol side-chain cleavage system by high-performance liquid chromatography with uv absorption monitoring. After the cholesterol side-chain cleavage system had been incubated and the reaction then halted by heat treatment, the product was converted into 3-one-4-en steroid showing intense absorption at 240 nm upon reaction with cholesterol oxidase. The converted steroids were then analyzed by normal-phase HPLC. In consequence, the catalytic activity of the reconstituted adrenocortical cytochrome P450sccsystem was readily assayed with a sensitivity more than 10-fold higher by this conversion. Also, it was shown that 22R-hydroxycholest-4-en-3-one could serve as a good substrate for cytochrome P450sccand that the 20R,22R-dihydroxy derivative could be clearly detected as a reaction intermediate in the reconstituted system.
