“…2Ϫ (221). However, rhodaneses are widely distributed enzymes with a number of functions and are found in plant cells and bacterial species incapable of thiosulfate oxidation (20,141,204). The purple nonsulfur phototrophic bacteria R. rubrum and R. capsulatus do not oxidize thiosulfate, although they produce a rhodanese (181).…”

SUMMARY The aerobic anoxygenic phototrophic bacteria are a relatively recently discovered bacterial group. Although taxonomically and phylogenetically heterogeneous, these bacteria share the following distinguishing features: the presence of bacteriochlorophyll a incorporated into reaction center and light-harvesting complexes, low levels of the photosynthetic unit in cells, an abundance of carotenoids, a strong inhibition by light of bacteriochlorophyll synthesis, and the inability to grow photosynthetically under anaerobic conditions. Aerobic anoxygenic phototrophic bacteria are classified in two marine (Erythrobacter and Roseobacter) and six freshwater (Acidiphilium, Erythromicrobium, Erythromonas, Porphyrobacter, Roseococcus, and Sandaracinobacter) genera, which phylogenetically belong to the α-1, α-3, and α-4 subclasses of the class Proteobacteria. Despite this phylogenetic information, the evolution and ancestry of their photosynthetic properties are unclear. We discuss several current proposals for the evolutionary origin of aerobic phototrophic bacteria. The closest phylogenetic relatives of aerobic phototrophic bacteria include facultatively anaerobic purple nonsulfur phototrophic bacteria. Since these two bacterial groups share many properties, yet have significant differences, we compare and contrast their physiology, with an emphasis on morphology and photosynthetic and other metabolic processes.

“…Further investigations revealed that rhodanese is widely distributed and is also found in plant roots and in bacteria [3]. Various bacteria have already been investigated and the degree of distribution of rhodanese has been discussed as a tool of potential taxonomic and diagnostic significance [4,5].…”

“…In B. subtilis and B. stearothermophilus, rhodanese is constitutive (8, 181). Rhodanese activity in photosynthetic bacteria does not correlate with the ability to metabolize thiosulfate or the pathway of thiosulfate metabolism (198). On the other hand, in Thiobacillus denitrificans rhodanese can be induced threefold by VOL.…”

“…Lang showed (83) that rhodanese catalyzes the formation of thiocyanate and sulfite from thiosulfate and cyanide: S2032-+ CN-SO32-+ SCN-Rhodanese has since been shown to catalyze a range of bacteria. The frequent observations of rhodanese in Thiobacillus species (18,31,32,90,100,145,173,175), in photosynthetic bacteria (159,198), and in Desulfphomaculatum (11) suggest that, in these organisms at least, it has a role in sulfur metabolism rather than one as a cyanide detoxifying agent. Rhodanese has also been found in several non-photosynthetic heterotrophic microorganisms (7,8,83,149,180,181).…”
