Fig. 9From: Impact of growth pH and glucose concentrations on the CodY regulatory network in Streptococcus salivariusThe regulation circuit of CodY in S. salivarius. The model suggests that the activity of CodY is modulated by growth pH and glucose concentrations via the amount of intracellular BCAA produced under each growth condition. Positive regulation is indicated by a plus sign and repression is indicated by a minus signBack to article page
