| Abstract: | FeMo-co, isolated from crystalliae molybdeaum-iron protein of Azotobacter vinelandii-230 nitrogenase, was purified by sephadex LH-20 gel column chromatography with NMF as solvent and separated by high-speed centrifugation(20 000xg, 30 min). The purified FeMo-co contained no amino acid. Laser Raman and electronic spectra of FeMo-co were investigated. The possibility that FeMo-co contaias S-S ligand, i-n conjunction with S ligand, is discussed |
