This family consists of various cation transport proteins (Trk) and V-type sodium ATP synthase subunit J or translocating ATPase J EC:3.6.1.34. These proteins are involved in active sodium up-take utilising ATP in the process. TrkH a member of the family Swiss:P76769 from E. coli is a hydrophobic membrane protein and determines the specificity and kinetics of cation transport by the TrK system in E. coli [2]. [1]. 8948101. Sequencing analysis of a 40.2 kb fragment of yeast chromosome X reveals 19 open reading frames including URA2 (5' end), TRK1, PBS2, SPT10, GCD14, RPE1, PHO86, NCA3, ASF1, CCT7, GZF3, two tRNA genes, three remnant delta elements and a Ty4 transposon.

TrkH and its homolog, TrkG, determine the specificity and kinetics of cation transport by the Trk system of Escherichia coli. Schlosser A, Meldorf M, Stumpe S, Bakker EP, Epstein W;. J Bacteriol 1995;177:1908-1910. [3]. 10629185. Trk1 and Trk2 define the major K(+) transport system in fission yeast. Calero F, Gomez N, Arino J, Ramos J;. J Bacteriol 2000;182:394-399. (from Pfam)
