- ... Two point mutants from the purple bacterium Rhodobacter capsulatus, both modified in the M protein of the photosynthetic reaction center, have been studied by flash-induced absorbance spectroscopy. These strains carry either the M231Arg leads to Leu or M43Asn leads to Asp mutations, which are located 9 and 15 angstroms, respectively, from the terminal electron acceptor QB. In the wild-type Rb. sph ...
