Regulation of P. aeruginosa quorum sensing by growth in low magnesium. Proteins highlighted blue are induced; those highlighted red are repressed. SAM, S-adenosylmethionine; ACP, acyl-carrier protein; LasI, 3OC12-HSL synthase; RhlI, C4-HSL synthase; C4-HSL, N-butyryl-l-homoserine lactone; 3OC12, N-(3-oxododecanoyl)-l-homoserine lactone; LasR and RhlR, transcriptional regulators. Lines marked + or − denote positive or negative regulation, respectively.
