Prokaryotic triterpenoids: O-alpha-D-glucuronopyranosyl bacteriohopanetetrol, a novel hopanoid from the bacterium Rhodospirillum rubrum.

Amino Acid Sequence of Cytochrome c’ from the Purple Photosynthetic Bacterium Rhodospirillum rubrum Sl*

The amino acid sequence of cytochrome c’ from the purple photosynthetic bacterium Rhodospirillum rubrum Sl has been determined and is consistent with homology to cytochrome c’ from the nonphotosynthetic bacterium Alcaligenes sp. NCIB 11015. There is 29% identity in the chosen alignment of these two proteins. R. rubrum cytochrome c’ is composed of a single peptide chain of 126 amino acid residue...

Identification and characterization of Rhodopseudomonas palustris TIE-1 hopanoid biosynthesis mutants.

Hopanes preserved in both modern and ancient sediments are recognized as the molecular fossils of bacteriohopanepolyols, pentacyclic hopanoid lipids. Based on the phylogenetic distribution of hopanoid production by extant bacteria, hopanes have been used as indicators of specific bacterial groups and/or their metabolisms. However, our ability to interpret them ultimately depends on understandin...

Carbon roadmap from syngas to polyhydroxyalkanoates in Rhodospirillum rubrum.

The gasification of organic waste materials to synthesis gas (syngas), followed by microbial fermentation, provides a significant resource for generating bioproducts such as polyhydroxyalkanoates (PHA). The anaerobic photosynthetic bacterium, Rhodospirillum rubrum, is an organism particularly attractive for the bioconversion of syngas into PHAs. In this study, a quantitative physiological analy...
