Rabbits treated with phenobarbital were given a single injection of allylisopropylacetamide (AIA) s.c. and/or heme i.v. Hepatic microsomes were isolated 1, 5 and 24 hours post injection and the microsomal contents of both total cytochrome P-450 chromophore, and the protein moiety of P-450 2 were determined by spectrophotometric and immunochemical methods respectively. AIA caused the levels of total P-450 chromophore and of P-450 2 protein to decline to 30% of the control values at 5 hours post-injection. Concurrent administration of heme with AIA diminished the decrease in the total microsomal content of P-450 chromophore but not in that of P-450 2 protein. These findings suggest that the destruction of the heme prosthetic group of P-450 by suicide substrates such as AIA may lead to an enhanced degradation of the apo-P-450.
