molecular function
    GO:0061579    N-acyl homoserine lactone synthase activity    Catalyzing the reaction: acyl-[acyl-carrier-protein] + S-adenosyl-L-methionine -> [acyl-carrier- protein] + S-methyl-5'-thioadenosine + N-acyl-L-homoserine lactone.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0009405    pathogenesis    The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.
    GO:0009372    quorum sensing    The process in which single-celled organisms monitor their population density by detecting the concentration of small, diffusible signal molecules produced by the cells themselves.
