Two types of signaling molecules have been identified: (1) shortpeptides, common to Gram-positive bacteria and (2) carboxy-acid derivativescommonly utilised by Gram-negative bacteria. Bacteria of the genus Streptomycesutilize butyrolactones as signaling molecules and thus form a distinct groupamong Gram-positives. This review focuses on two model regulatory systemsbased on carboxy-acid derivatives; the regulation of bioluminescence in Vibriofisheri and the regulation of streptomycin biosynthesis in Streptomyces griseus.}, type={Text}, title={Bacterial small signaling molecules}, URL={http://rcin.org.pl/Content/137709/PDF/POZN271_172915_biotechnologia-2002-no4-pawlik.pdf}, keywords={biotechnology}, }
