Within the complex with two substrate binding domains, the two domains interact in a cooperative manner and enhance the transport capacity -, 655339 7.6.2.9 ATP + H2O + quaternary amine-[quaternary amine-binding protein][side 1] = ADP + phosphate + quaternary amine[side 2] + [quaternary amine-binding protein][side 1] busA locus encodes the glycine betaine uptake system, which expression is reduced by overexpression of busR gene encoding a DNA binding protein 656842 7.6.2.9 ATP + H2O + quaternary amine-[quaternary amine-binding protein][side 1] = ADP + phosphate + quaternary amine[side 2] + [quaternary amine-binding protein][side 1] OpuA is an osmoprotectant uptake system which imports glycine and betaine. It consists of three components, the ATPase OpuAA, the integral membrane protein OpuAB and the extracellular substrate binding domain OpuAC. The ABC transporter couples ATP hydrolysis with substrate translocation across the membrane in a vectorial manner 656531 7.6.2.9 ATP + H2O + quaternary amine-[quaternary amine-binding protein][side 1] = ADP + phosphate + quaternary amine[side 2] + [quaternary amine-binding protein][side 1] the mechanistica stoichiometry is 2 -, 656670 7.6.2.9 ATP + H2O + quaternary amine-[quaternary amine-binding protein][side 1] = ADP + phosphate + quaternary amine[side 2] + [quaternary amine-binding protein][side 1] the osmotic activation of the transporter is set by the bulk charge in the lipid headgroup region of the membrane, indicating that electrostatic interactions between lipids and the transporter are intrinsic to the osmosensing mechanism 655328
