Blue shifts in bacteriochlorophyll absorbance correlate with changed hydrogen bonding patterns in light-harvesting 2 mutants of Rhodobacter sphaeroides with alterations at alpha-Tyr-44 and alpha-Tyr-45.
A combination of Fourier-Transform (FT) resonance Raman spectroscopy and site-directed mutagenesis has been used to examine the function of two highly conserved aromatic residues, alpha-Tyr-44 and alpha-Tyr-45, in the light-harvesting 2 (LH2) complex of the photosynthetic bacterium Rhodobacter sphae...
