[ATPase activity and K+ transport in membranes of anaerobically grown trk-mutants of Escherichia coli].

Biokhimiia (Moscow, Russia) - 1 Jul 1993

Trchunian A A, Vasilian A V

Abstract excerpt

A notable (twofold) increase in N,N'-dicyclohexylcarbodiimide (DCCD)-sensitive ATPase activity at increasing concentrations of K+ ion--from zero to 100 mM was found in isolated membranes of anaerobically grown E. coli. This was also observed during changing of Rb+ concentration (but not that of Na+, CL- or NO3-) and only in the wild precursor strain and trkG (but not in trkA, trkE, or trkH mutants). The...
