Accession numbers NC_009767
Background Roseiflexus is a filamentous anoxygenic phototroph, one of the green filamentous bacteria. This lineage is placed on the deepest branch of all photosynthetic bacteria. R.castenholzii HL08 was isolated from a microbial mat in a Japanese hot spring. It is able to grow photoheterotrophically under anaerobic light conditions and also chemoheterotrophically under aerobic dark conditions. Optimal growth occurs at 50 degrees C and pH 7.5-8.0. The cells contain bacteriochlorophyll (Bchl) a and gamma-carotene derivatives as photosynthetic pigments, but lack Bchl c and chlorosomes, a type of light-harvesting structure. Like many other phototrophic bacteria it has gliding motility. Comparative genomics indicates that it appears to have the genetic capacity for CO2 reduction via the 3-hydroxypropionate pathway (adapted in part from PubMed 11837302 and 17635550). (EBI Integr8)
