Photosynthesis at the far-red region of the spectrum in Acaryochloris marina

Abstract Acaryochloris marina is an oxygenic cyanobacterium that utilizes far–red light for photosynthesis. It has an expanded genome, which helps in its adaptability to the environment, where it can survive on low energy photons. Its major light absorbing pigment is chlorophyll d and it h...

Oxygenic photosynthesis Acaryochloris species Chlorophyll d Photosystem Phycobillisomes P740 Abstract Acaryochloris marina is an oxygenic cyanobacterium that utilizes far–red light for photosynthesis. It has an expanded genome, which helps in its adaptability to the environment, where it can survive on low energy photons. Its major light absorbing pigment is chlorophyll d and it has α–carotene as a major carotenoid. Light harvesting antenna includes the external phycobilin binding proteins, which are hexameric rods made of phycocyanin and allophycocyanins, while the small integral membrane bound chlorophyll binding proteins are also present. There is specific chlorophyll a molecule in both the reaction center of Photosystem I (PSI) and PSII, but majority of the reaction center consists of chlorophyll d. The composition of the PSII reaction center is debatable especially the role and position of chlorophyll a in it.
