SST3. OC Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacteriales; OC Enterobacteriaceae; Enterobacter. OX NCBI_TaxID=1216470; RN [1] RP NUCLEOTIDE SEQUENCE. RC STRAIN=SST3; RX PubMed=23045495; DOI=10.1128/JB.01469-12; RA Gan H.M., McGroty S.E., Chew T.H., Chan K.G., Buckley L.J., RA Savka M.A., Hudson A.O.; RT "Whole-Genome Sequence of Enterobacter sp. Strain SST3, an Endophyte RT Isolated from Jamaican Sugarcane (Saccharum sp.) Stalk Tissue."; RL J. Bacteriol. 194:5981-5982(2012). CC -!- FUNCTION: One of the components of the high-affinity ATP-driven CC potassium transport (or KDP) system, which catalyzes the CC hydrolysis of ATP coupled with the exchange of hydrogen and CC potassium ions (By similarity). CC -!- CATALYTIC ACTIVITY: ATP + H(2)O + K(+)(Out) = ADP + phosphate + CC K(+)(In). CC -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein CC (By similarity). CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC CC 3.A.3) family. Type IA subfamily. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data.
