Disease relevance of Chloroflexus

• 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 [1].
• The gene bchG, coding for bacteriochlorophyll a synthase from a variety of green sulfur bacteria and the filamentous anoxygenic phototrophic bacteria, Chloroflexus aurantiacus, Chloronema sp., and Roseiflexus castenholzii HL08, was partially sequenced and compared [2].
• In an examination of a microbial mat sample from Octopus Spring, Yellowstone National Park (USA), we could readily identify chemical structures with 13C contents which were diagnostic for the phototrophic organisms such as cyanobacteria and Chloroflexus [3].

High impact information on Chloroflexus

• Propionyl-coenzyme A synthase from Chloroflexus aurantiacus, a key enzyme of the 3-hydroxypropionate cycle for autotrophic CO2 fixation [4].
• A bicyclic autotrophic CO2 fixation pathway in Chloroflexus aurantiacus [1].
• The stability of tetrameric malate dehydrogenase from the green phototrophic bacterium Chloroflexus aurantiacus (CaMDH) is at least in part determined by electrostatic interactions at the dimer-dimer interface [5].
• Malate dehydrogenase (MDH) from the moderately thermophilic bacterium Chloroflexus aurantiacus (CaMDH) is a tetrameric enzyme, while MDHs from mesophilic organisms usually are dimers [6].
• The biochemical and biophysical data obtained for arsenite oxidase in the green filamentous bacterium Chloroflexus aurantiacus allow a structural model of the enzyme's membrane association to be proposed [7].

Chemical compound and disease context of Chloroflexus

• Functioning of quinone acceptors in the reaction center of the green photosynthetic bacterium Chloroflexus aurantiacus [8].
• Photosynthetic sulfide oxidation by Chloroflexus aurantiacus, a filamentous, photosynthetic, gliding bacterium [9].
• Two strains of the gliding phototrophic bacterium Chloroflexus aurantiacus were investigated for the presence of lipopolysaccharide (LPS) [10].
• Bacteriochlorophyll c formation via the C5 pathway of 5-aminolevulinic acid synthesis in Chloroflexus aurantiacus [11].
• Biosynthesis of 5-aminolevulinic acid (ALA) in Chloroflexus aurantiacus, a thermophilic bacterium forming bacteriochlorophyll c, is shown to proceed via the C5 pathway by demonstrating (1) the specific labeling of its chlorin ring with [1 - 13C]glutamate and (2) the enzyme activity to produce ALA from glutamate in a cell-free extract [11].

Anatomical context of Chloroflexus

• Absence of a characteristic cell wall lipopolysaccharide in the phototrophic bacterium Chloroflexus aurantiacus [10].
