The reactivity of spinach plastocyanin mutants with inorganic oxidants [Fe(CN)6]3– and [Co(phen)3]3+
Abstract
Stopped-flow rate constants for the oxidation of spinach plastocyanin PCuI mutants Leu12Glu, Leu12Asn, Asp42Asn and Tyr83Phe have been determined, and are discussed in terms of two-site reactivity for electron transfer.
