Two photosystem II-associated chlorophyll-protein complexes of Synechococcus sp. strain PCC 7002 were identified. Their polypeptide compositions were similar to those of chlorophyll-containing antenna complexes of other cyanobacteria. Strain GT8B did not possess the complex responsible for 695-nm fluorescence and was unable to grow photoautotrophically; hence, this complex is necessary for photosystem II function in vivo.
已鉴定出集胞藻属PCC 7002菌株的两种与光系统II相关的叶绿素-蛋白质复合物。它们的多肽组成与其他蓝细菌的含叶绿素天线复合物相似。GT8B菌株不具备负责695纳米荧光的复合物,无法进行光合自养生长;因此,该复合物是光系统II在体内发挥功能所必需的。
