Abstract excerpt
A study has been made of the nature of H+-K+-exchanges in the strain E. coli AN 120 with mutation in gene uncA401 (the defect in Mg++-Ca++-ATPase) and in the strain E. coli AN 382 with mutation in gene uncB (F0 is insensitive to N,N1-dicyclohehylcarbodiimide, DCCD). It was shown in E. coli AN 120 that no ATP-dependent and DCCD-sensitive TrkA system operates, exchanging 2H+ from a cell for K+ of the medium and...
