Vibrio alginolyticus contained two adjacent genes, ktrA and ktrB, which encode a new type of bacterial K⁺-uptake system. KtrA and KtrB are peripheral and integral membraneproteins, respectively. Six of the nine sequenced bacterial genomescontain homologs to both ktrA and ktrB, suggesting that KtrABis widespread.
