PHOTOSYNTHETIC REACTION CENTER MUTANT WITH GLY M203 REPLACED WITH LEU
Overview
The role of a water molecule (water A) located between the primary, electron donor (P) and first electron acceptor bacteriochlorophyll (B(A)), in the purple bacterial reaction center was investigated by mutation of, glycine M203 to leucine (GM203L). The x-ray crystal structure of the, GM203L reaction center shows that the new leucine residue packs in such a, way that water A is sterically excluded from the complex, but the, structure of the protein-cofactor system around the mutation site is, largely undisturbed. The results of absorbance and resonance Raman, spectroscopy were consistent with either the removal of a hydrogen bond, interaction between water A and the keto carbonyl group of B(A) or a, change in the local electrostatic environment of this carbonyl group., Similarities in the ...
