Abstract

Four out of five soluble electron transport iron proteins of Thiocapsa pfennigii plus the particulate cytochromes have been found to be analogous to those of Chromatium vinosum strain D. In addition to ferredoxin, high potential iron-sulfur protein. cytochrome c′, and cytochrome c-552(550), T. pfennigii contains a cytochrome c-552(545) not previously isolated from photosynthetic bacteria. It is concluded that T. pfennigii is more closely related to C. vinosum than to Rhodopseudomonas viridis, the only other known bacterial species having bacteriochlorophyll b.
