Lineage
Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as
ECK3276
Summary
Although normally required for Trk activity, overproduction of TrkG or TrkH alone increases K+ transport in a trkA mutant strain (Buurman, 2004). [More information is available at EcoGene: EG11019]. trkA mutants were identified in a kdp background as requiring significantly elevated levels of K+ for growth . trkA encodes part of a K+ transport system . [More information is available at EcoCyc: EG11019].
