A cambialistic superoxide dismutase in the thermophilic photosynthetic bacterium Chloroflexus aurantiacus.
Superoxide dismutase from the thermophilic anoxygenic photosynthetic bacterium Chloroflexus aurantiacus was cloned, purified, and characterized. This protein is in the manganese- and iron-containing family of superoxide dismutases and is able to use both manganese and iron catalytically. This appears to be the only soluble superoxide dismutase in C. aurantiacus. Iron and manganese cofactors wer...
متن کاملBiosynthetic controls on the 13C contents of organic components in the photoautotrophic bacterium Chloroflexus aurantiacus.
To assess the effects related to known and proposed biosynthetic pathways on the (13)C content of lipids and storage products of the photoautotrophic bacterium Chloroflexus aurantiacus, the isotopic compositions of bulk cell material, alkyl and isoprenoid lipids, and storage products such as glycogen and polyhydroxyalkanoic acids have been investigated. The bulk cell material was 13 per thousan...
متن کاملGlycine Cleavage Powers Photoheterotrophic Growth of Chloroflexus aurantiacus in the Absence of H2
Chloroflexus aurantiacus is an anoxygenic phototrophic bacterium. Its unique CO2 fixation pathway and primitive light-harvesting antenna complexes have attracted extensive research attentions. In this work, we investigated the photoheterotrophic growth of C. aurantiacus J-10-fl using acetate [at 55°C and without H2(g)]. The results indicate that glycine can promote anaerobic biomass production ...
متن کاملA bicyclic autotrophic CO2 fixation pathway in Chloroflexus aurantiacus.
Phototrophic CO(2) assimilation by the primitive, green eubacterium Chloroflexus aurantiacus has been shown earlier to proceed in a cyclic mode via 3-hydroxypropionate, propionyl-CoA, succinyl-CoA, and malyl-CoA. The metabolic cycle could be closed by cleavage of malyl-CoA affording glyoxylate (the primary CO(2) fixation product) with regeneration of acetyl-CoA serving as the starter unit of th...
متن کاملRole of the AcsF protein in Chloroflexus aurantiacus.
The green phototrophic bacteria contain a unique complement of chlorophyll pigments, which self-assemble efficiently into antenna structures known as chlorosomes with little involvement of protein. The few proteins found in chlorosomes have previously been thought to have a primarily structural function. The biosynthetic pathway of the chlorosome pigments, bacteriochlorophylls c, d, and e, is n...
