The M-subunit primary structure of the reaction centre (RC) from Chloroflexus aurantiacus composed of 306 amino acid residues has been determined by parallel analysis of the protein and corresponding DNA. The blocked N-terminus as well as replacement of the essential histidine liganding Mg of an accessory bacteriochlorophyll in purple bacteria by leucine distinguishes the M-subunit of Chloroflexus RC from that of purple bacteria.
通过对蛋白质和相应DNA的平行分析,已确定橙色绿屈挠菌反应中心(RC)的M亚基一级结构由306个氨基酸残基组成。橙色绿屈挠菌RC的M亚基与紫色细菌的不同之处在于,其N端被封闭,并且紫色细菌中一个辅助细菌叶绿素与镁结合的必需组氨酸被亮氨酸取代。
