Thin film voltammetry of wild type and mutant reaction center proteins from photosynthetic bacteria.

The journal of physical chemistry. B - 31 Mar 2011

Abstract excerpt

Photosynthetic reaction centers (RC) convert light into electrical potential via a series of electron transfers between protein-bound, redox-active cofactors. Direct voltammetry was used to characterize the RC protein from Rhodobacter sphaeroides and mutants with focus on the primary electron donor (P) cofactor. Cyclic voltammetry (CV) and square wave voltammetry (SWV) of lipid and polyion films of RCs revealed...
