Proton release due to manganese binding and oxidation in modified bacterial reaction centers.

Biochemistry - 11 Oct 2005

Kálmán L, Thielges M C, Williams J C, Allen J P

Abstract excerpt

The pH dependence of binding and oxidation of Mn2+ in highly oxidizing reaction centers with designed metal-binding sites was characterized by light-minus-dark optical difference spectroscopy and direct measurements of proton uptake/release. These mutants bind a Mn2+ ion that can efficiently transfer an electron to the oxidized bacteriochlorophyll dimer, as described earlier [Thielges et al. (2005) Biochemistry...
