Role of the Longest Arm of Phycobilisome Core-Membrane Linker in Assembling the Phycobilisomes From Synechocystis sp. PCC 6803.

Frontiers in bioscience (Landmark edition) - 22 Dec 2025

Niu Nannan, Chen Ning, Feng Huanhuan, Du Xueli

Abstract excerpt

BACKGROUND: The phycobilisomes (PBS) of cyanobacteria and red algae are unique light-harvesting protein-pigment complexes that utilize bilin derivatives for light absorption and energy transfer. These extramembranous mega-Dalton complexes are specifically organized and anchored to photosystem II (PSII) via the multi-domain core-membrane linker (LCM). While Arm2 is the longest segment in LCM domain, its specific...
