Non-conventional octameric structure of C-phycocyanin

2021

Takuo Minato and colleagues determine the crystal and cryo-EM structures of the native C-phycocyanin (CPC) from the thermophilic cyanobacterium, Thermoleptolyngbya sp. O77, which was found to adopt both a conventional hexameric structure and a novel octameric assembly. These findings provide new insights into the assembly of CPCs and their mechanism of energy transfer.
