Tryptophan pyrrolase in haem regulation. The mechanism of the opposite effects of tryptophan on rat liver 5-aminolaevulinate synthase activity and the haem saturation of tryptophan pyrrolase.
1. Administration of tryptophan to starved rats causes a rapid decrease in liver 5-aminolaevulinate synthase activity associated with an increase in the haem saturation of tryptophan pyrrolase. Both effects are maximally produced at 30 min by a 100 mg/kg body wt. dose of tryptophan. 2. Pb2+ prevents...
