Notes

[back to top]


Although normally required for Trk activity, overproduction of TrkG or TrkH alone increases K+ transport in a trkA mutant strain (Buurman, 2004). SapD(TrkE) is required for TrkAH activity and stimulates TrkAG transport rate (Bossemeyer, 1989; Dosch, 1991; Harms, 2001). TrkAG may be inactive during anaerobic growth (Trchounian, 1994). Trk-mediated transport is driven by proton motive force, but requires a high ATP concentration for maximal activity, presumably because ATP-binding is needed to activate SapD (Harms, 2001).[4]
