Porphyrin biosynthesis-immobilized enzymes and ligands. IX. Studies on δ-aminolaevulinate synthetase from cultured soybean cells

Soybean callus δ-aminolaevulinate synthetase (ALA-S) has been covalently attached to Sepharose 4B. The optimal conditions for binding have been determined. The water-insoluble ALA-S retained 40% of the activity of the original soluble preparation, the coupling yield was also high. Sepharose - ALA-S...
