Abstract
It was shown that DCCD-sensitive ATPase activity of isolated membranes and preparations of F1F0 only from anaerobically grown E. coli depended on K+ activity. F1F0 include two additional proteins which correspond to the Trk system. The data improve the possibility to form supercomplex (F1F0-Trk) functioning as the H(+)-K(+)-pump.
摘要
结果表明，仅从厌氧生长的大肠杆菌分离的膜和F1F0制剂的对二环己基碳二亚胺（DCCD）敏感的ATP酶活性取决于钾离子（K+）活性。F1F0包含另外两种与Trk系统相对应的蛋白质。这些数据提高了形成作为H(+)-K(+)-泵发挥作用的超复合物（F1F0-Trk）的可能性。
