Scientists Shed New Light on Photosynthetic Supercomplex StructureMay 29, 2019
The complex is unique in size, the largest photosynthetic supercomplex with a known molecular structure, and in complexity with more than 700 different molecules (mostly light-harvesting molecules) making up the complete structure. The scientists also found that there are 591 chlorophylls in the PSI-IsiA supercomplex, by far the largest number of bound pigments in any of the photosynthetic supercomplexes with known structures.
This supercomplex is produced by a cyanobacterium under low iron environment or excessive light fluxes in the lab. The ability of the cyanobacterium to express this complex while under stress plays an important role in their survival under such conditions.
