Isolation and characterization of bacteriochlorophyll-protein complexes from an aerobic bacterium,Pseudomonas radiora

摘要

Bacteriochlorophyll(Bchl)-protein complexes were isolated from a strictly aerobic and facultative methylotrophic bacteriumPseudomonas radiorastrain MD-1. They were identified as the reaction center (RC)-B870 and the B870 complexes on the basis of their absorption spectra, light induced spectral changes and polypeptide compositions. The RC-B870 complex of this bacterium showed similar properties to those of typical purple photosynthetic bacteria, and containedc-type cytochrome which was oxidized upon illumination.
