Erythroid 5-aminolevulinate synthetase from trout (Salmo gairdneri R.).
A mitochondrial and cytosolic erythroid ALA-synthetase have been found in trout. The polypeptide existent in the cytosol is probably a precursor of the 90,000 mol. wt mitochondrial ALA-synthetase. The erythroid ALA-synthetase is about 20,000 mol. wt larger than the hepatic enzyme. The differences in mol. wt and catalytic properties between erythroid and hepatic enzyme support the existence of two forms of the ALA-synthetase in teleostei.
