Influence of Asn/His L166 on the hydrogen-bonding pattern and redox potential of the primary donor of purple bacterial reaction centers.

Biochemistry - 11 Mar 1997

Ivancich A, Mattioli T A

Abstract excerpt

The primary electron donor (P) of the photosynthetic reaction center (RC) from the purple bacterium Rhodobacter (Rb.) sphaeroides is constituted of two bacteriochlorophyll molecules in excitonic interaction. The C2 acetyl carbonyl group of one of the two bacteriochlorophyll molecules (PL), the one more closely associated with the L polypeptide subunit, is engaged in a hydrogen bond with histidine L168, while the...
