The terminal phycobilisome emitter, LCM: A light-harvesting pigment with a phytochrome chromophore.
Photosynthesis relies on energy transfer from light-harvesting complexes to reaction centers. Phycobilisomes, the light-harvesting antennas in cyanobacteria and red algae, attach to the membrane via the multidomain core-membrane linker, L(CM). The chromophore domain of L(CM) forms a bottleneck for funneling the harvested energy either productively to reaction centers or, in case of light overlo...
متن کاملLight-Harvesting Complex: Rings of light
The atomic structure of the bacterial light-harvesting complex helps to explain how the energy of sunlight is efficiently absorbed and transferred between bacteriochlorophyll molecules towards the reaction centre.
متن کاملTranscriptional regulation of the stress-responsive light harvesting complex genes in Chlamydomonas reinhardtii.
Dissipating excess energy of light is critical for photosynthetic organisms to keep the photosynthetic apparatus functional and less harmful under stressful environmental conditions. In the green alga Chlamydomonas reinhardtii, efficient energy dissipation is achieved by a process called non-photochemical quenching (NPQ), in which a distinct member of light harvesting complex, LHCSR, is known t...

متن کاملPhycobilisome Mobility and Its Role in the Regulation of Light Harvesting in Red Algae.
Red algae represent an evolutionarily important group that gave rise to the whole red clade of photosynthetic organisms. They contain a unique combination of light-harvesting systems represented by a membrane-bound antenna and by phycobilisomes situated on thylakoid membrane surfaces. So far, very little has been revealed about the mobility of their phycobilisomes and the regulation of their li...
