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.

that it was a weak enough disease to use the anibiotic to kill it off if it were cancer they would have to use cemo therapy witch is EXTREMLY harmful to the pasient thats how my dad died so i know

There are 6 common types of pesticide that are recognized and seen quite often:
1. Insecticides which are mainly used to kill insects, ticks, and mites.
2. Herbicides which are mainly used to kill weeds.
3. Fungicides which are mainly used to kill mildew and other fungi.
4. Rodenticides which are mainly used to kill mice, rats, and other rodents.
5. Disinfectants which are mainly used to kill bacteria and mold.
6. Wood Preservatives which mainly protects wood from fungus and insects invading it's system.
There are different types of families for pesticide as well at a much deeper level.
