A pyridinol acyl cofactor in the active site of [Fe]-hydrogenase evidenced by the reactivity of model complexes

摘要

Understanding the complex: The decomposition reaction of a water-soluble complex (see scheme; 1) in H_2O confirms the existence of a unique bidentate pyridinol cofactor in [Fe]-hydrogenase. This unique moiety is confirmed for the first time by the decomposition of a well-defined model complex containing a pyridinyl methyl acyl ligand.
