By decarboxylating arginine, Escherichia coli's severe acid resistance response is arginine-dependent.
A proton is actually exported with each turnover of the membrane antiporter AdiC, which catalyzes the decarboxylation product agmatine's efflux together with arginine influx.
<h3>Extreme acid resistance is facilitated by a bacterial arginine-agmatine exchange transporter.</h3>
- We produced and purified the transport protein using the adiC coding sequence under the control of a tetracycline promoter in an E. coli vector, with a yield of roughly 10 mg/liter bacterial culture.
- In detergent micelles and lipid membranes, the protein is a homodimer, according to tests using the cross-linking of glutaraldehyde.
- In liposome form, purified AdiC exchanges arginine and agmatine in a closely linked, electrogenic manner.
- The dissociation constant for Arg, as calculated by isothermal titration calorimetry, is in the same range as the K(m) value obtained through kinetic analysis, which is around 80 microm.

DescriptionPopulation density is a measurement of population per unit area, or exceptionally unit volume; it is a quantity of type number density. It is frequently applied to living organisms, most of the time to humans. It is a key geographical term.
