1.A.1.13.9
K+ channel of 387 aas and 2 TMSs, KchA.  KchA is essential for growth at low concentrations of K+. This K+ uptake system is essential for gastric colonization and the persistence of H. pyloriin the stomach (Stingl et al. 2007). This protein is of the two-transmembrane RCK (regulation of K+ conductance) domain family (Stingl et al. 2007).
