title: Thioredoxin from Rhodospirillum rubrum: primary structure and relation to thioredoxins from other photosynthetic bacteria.
abstract: Thioredoxin was isolated from a photosynthetic purple nonsulfur bacterium, Rhodospirillum rubrum, and its primary structure was determined by high-performance tandem mass spectrometry. The sequence identity of R. rubrum thioredoxin to Escherichia coli thioredoxin was intermediate to those of the Chlorobium thiosulfatophilum and Chromatium vinosum proteins. The results indicate that R. rubrum has an NADP-thioredoxin system similar to that of other photosynthetic purple bacteria.
