The Rex regulator is a unique transcription factor that respond to intracellular redox potential and negatively control expression of genes involved in energy metabolism and fermentative growth in Gram-positive bacteria including Streptomyces coelicolor, Bacillus subtilis, Staphylococcus aureus, and Thermus aquaticus. Nicotinamide adenine dinucleotides (NAD(H)) play important role in different biological processes, including redox cellular balance. During the catabolism of carbohydrates, NAD+ is reduced to NADH by glycolytic enzymes. The NADH formed is re-oxidized back either by the electron transport chain under aerobic conditions, or by NADH-linked fermentative enzymes under anaerobic conditions. more
