Monitoring intracellular redox conditions in the endoplasmic reticulum of living yeasts.

abstract：:Rifampicin is a principal drug used to combat infections by mycobacteria and related organisms. Most strains of Mycobacterium are able to inactivate this antibiotic by ribosylation via an ADP-ribosylated intermediate. We found that this inactivation was inhibited by light at levels similar to those prevailing in labor...
