Red blood cell rhodanese: Its possible role in modulating δ-aminolaevulinate synthetase activity in mammals
1. 1. The optimum conditions for measuring rhodanese activity in human erythrocytes were established. The mean control values for males (112 nmol SCN/30 min/mg protein) and females (127 nmol SCN/30 min/mg protein) were determined. 2. 2. Rhodanese activity was measured in different porphyric patients...
