The action of haem, haemoglobin and other haemoproteins on crude and purified delta-aminolaevulate dehydratase of human erythrocyte is described. The results show a feedback inhibition by haem of porphyrin synthesis at the level of erythrocyte delta-aminolaevulate dehydratase. Some kinetic characteristics of this inhibition are described.
本文描述了血红素、血红蛋白及其他血红素蛋白对人红细胞粗提和纯化的δ-氨基-γ-酮戊酸脱水酶的作用。结果表明,在红细胞δ-氨基-γ-酮戊酸脱水酶水平上,血红素对卟啉合成具有反馈抑制作用。本文还描述了这种抑制作用的一些动力学特征。
