Jung K, Veen M, Altendorf K. K+ and ionic strength directly influence the autophosphorylation activity of the putative turgor sensor KdpD of Escherichia coli. J Biol Chem. 2000;275:40142-7 pubmed
Jung K, Hamann K, Revermann A. K+ stimulates specifically the autokinase activity of purified and reconstituted EnvZ of Escherichia coli. J Biol Chem. 2001;276:40896-902 pubmed
..Whether K(+) accumulation, which is one of the first responses of E. coli after an osmotic upshift, is related to the stimulation of the EnvZ autokinase activity in vivo is discussed. ..

..Instead, various--mainly intracellular parameters--that are related to changes of environmental conditions influence the activities of KdpD. ..
