Tryptophan pyrrolase in haem regulation. The mechanism of the permissive effect of cortisol on the enhancement of 5-aminolaevulinate synthase activity by 2-allyl-2-isopropylacetamide in the adrenalectomized-rat liver.

Abstract

The decreased ability of 2-allyl-2-isopropropylacetamide to enhance liver 5-amino-laevulinate synthase activity in the adrenalectomized rat is not associated with a marked depletion of the already low amount of tryptophan pyrrolase haem. Cortisol permits the porphyrogen markedly to enhance synthase activity by rendering it capable of causing a stronger depletion of pyrrolase haem, presumably as result of hormonal induction of pyrrolase synthesis.
