In the large linker ArcE polypeptide of the phycobilisome (PBS) from the cyanobacterium Synechocystis sp. PCC 6803, the chromophore-containing 26-kDa domain was deleted with consequent disturbance of the main PBS functions. Phycobilisomes in mutant cells staying in contact with photosystem I cannot transfer energy to the photosystem II. Under the bright light conditions, the interaction of PBSs with the photoprotective orange carotenoid protein in the mutant was lost and the implementation of transition states 1 and 2 of the pigment apparatus was significantly reduced.
在蓝藻集胞藻PCC 6803的藻胆体（PBS）的大连接体ArcE多肽中，含发色团的26 kDa结构域被删除，从而干扰了主要的PBS功能。与光系统I保持接触的突变细胞中的藻胆体无法将能量转移到光系统II。在强光条件下，突变体中藻胆体与光保护橙色类胡萝卜素蛋白的相互作用丧失，色素机构的过渡态1和过渡态2的实现显著减少。
