Oral administration of triacetyloleandomycin (TAO), 1 mmol/kg/day for 7 days to mature male New Zealand White rabbit results in a significant increase in the content of liver microsomal cytochrome P-450. This increase is accompanied by the occurrence on sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the microsomes of a strong band in the zone of electrophoretic mobility associated with the LM3 isozymes and the stimulation of a number of monooxygenase activities of these microsomes including aminopyrine, chlorcyclizine, TAO, and erythromycin demethylation as well as 2-OH-estradiol and 6 beta OH-testosterone hydroxylation. Cytochrome P-450 LM3 (TAO) from these liver microsomes, purified to electrophoretic homogeneity, had Mr = 52,000 as determined by calibrated sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Comparison with isozymes LM3a, LM3b, and LM3c isolated from control animals, by a number of criteria including spectral data, amino acid content, NH2-terminal sequence analysis, peptide mapping, immunological properties, and monooxygenase activities of reconstituted system, indicated that isozymes LM3 (TAO) and LM3b are very similar, if not identical, proteins. We conclude that TAO must be considered as a new type of inducer of microsomal cytochrome P-450 from rabbit liver.
