Substrate activity of Rh(III)ATP with phosphoglycerate kinase and the role of the metal ion in catalysis.

Abstract

An exchange-inert Rh(H2O)4ATP complex showed a one-turnover substrate activity with yeast phosphoglycerate kinase. Transfer of the phosphoryl group between ATP and 3-phosphoglycerate occurs with both substrates in the coordination sphere of the metal ion. Because of the slow ligand exchange rates of Rh3+, the reaction product 1,3-diphosphoglycerate (1,3… (More)
