Purification of erythrocyte cytochrome P-450 from goat and chick.

Cytochrome P-450 has been purified from goat and chick erythrocytes and characterized. Goat erythrocyte cytochrome P-450 content was higher than that of chick erythrocytes cytochrome P-450. Elution profile of purified protein from DEAE-cellulose column showed a single peak. The catalytic activities of aminopyrine-N-demethylase and acetanilide hydroxylase were found to be higher in purified proteins. Molecular weight was determined by SDS-polyacrylamide gel electrophoresis.
