[N,N'-dicyclohexylcarbodiimide-sensitive K+-dependent H+ secretion from anaerobically grown E. coli cells]

Dependence of N,N'-dicyclohexylcarbodiimide (DCC)-sensitive H+ secretion of K+ activity was discovered. This dependence took place only in anaerobically grown bacteria, and only at the structural intact DCC-sensitive H+-ATPase complex and K+-ionophore Trk.
