EPR characterization of genetically modified reaction centers of Rhodobacter capsulatus.

Biochemistry - 3 Jul 1990

Bylina E J, Kolaczkowski S V, Norris J R, Youvan D C

Abstract excerpt

Electron paramagnetic resonance (EPR) has been used to investigate the cation and triplet states of Rhodobacter capsulatus reaction centers (RCs) containing amino acid substitutions affecting the primary donor, monomeric bacteriochlorophylls (Bchls), and the photoactive bacteriopheophytin (Bphe). The broadened line width of the cation radical in HisM200----Leu and HisM200----Phe reaction centers, whose primary...
