Promoter activity of mleR in the presence of malate. Influence of L-malate (25 mM, not neutralized) on the promoter activity of wildtype S. mutans carrying mleRp-luc in BMS medium under anaerobic conditions. Open diamond, growth without malate; Grey diamond, RLU, no addition of L-malate; Triangle, RLU, addition of L-malate after 30 min; Circle, RLU, addition after 2.5 hours; Square, RLU, addition after 4.5 hours.
