General Information

General Information Comment Organism
evolution BchE and ChlA/AcsF are mainly identified in anoxygenic photosynthetic bacteria and plants, respectively. Some photosynthetic bacteria have either both or one of the two enzymes. The phylogenetic relationships imply that both chlE/bchE and chlA/acsF genes had been the MPE cyclase genes inherited by a cyanobacterial common ancestor, and chlE has been later lost in several lineages. The chlA gene has persisted in all cyanobacterial lineages. A gene duplication of chlA to form chlAI and chlAII appears to have occurred in an early phase of evolution of cyanobacteria.
