The amino acid sequence of a bacteriochlorophyll a-protein from the green photosynthetic bacterium Prosthecochloris aestuarii strain 2K has been determined. Use was made of a tentative sequence deduced from a 2.8-A electron density map of the protein to help locate sequenced peptides. The polypeptide chain consists of 366 amino acids. The identities of 5 amino acids that ligand to the magnesium atoms of 5 of the 7 bacteriochlorophyll molecules present in each subunit of the trimeric complex have been confirmed as histidines.
已确定来自绿色光合细菌河口原绿球藻2K菌株的细菌叶绿素a蛋白的氨基酸序列。利用从该蛋白2.8埃电子密度图推导的暂定序列来帮助定位测序的肽段。多肽链由366个氨基酸组成。三聚体复合物每个亚基中存在的7个细菌叶绿素分子中的5个与镁原子配位的5个氨基酸已被确认为组氨酸。
