The chemical design or redesign of proteins with significant biological activity presents formidable challenges. Ion channels offer advantages for such design studies because one can examine the function of single molecular entities in real time. Gramicidin channels are attractive for study because of their known structure and exceptionally well-defined(More)
Bacterial pathogens like Mycobacterium tuberculosis (Mtb) encounter acidic microenvironments in the host and must maintain their acid-base homeostasis to survive. A genetic screen identified two Mtb strains that cannot control intrabacterial pH (pHIB) in an acidic environment; infection with either strain led to severe attenuation in mice. To search for(More)
