RT   "The phzI gene of Pseudomonas aureofaciens 30-84 is responsible for the
RT   production of a diffusible signal required for phenazine antibiotic
RT   production.";
RL   Gene 168:49-53(1996).
CC   -!- FUNCTION: Required for the synthesis of a yet unknown N-aceyl-
CC       homoserine lactone (N-aceyl-HSL), an autoinducer molecule which binds
CC       to PhzR and thus regulates phenazine production.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a fatty acyl-[ACP] + S-adenosyl-L-methionine = an N-acyl-L-
CC         homoserine lactone + H(+) + holo-[ACP] + S-methyl-5'-thioadenosine;
CC         Xref=Rhea:RHEA:10096, Rhea:RHEA-COMP:9685, Rhea:RHEA-COMP:14125,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:17509, ChEBI:CHEBI:55474,
CC         ChEBI:CHEBI:59789, ChEBI:CHEBI:64479, ChEBI:CHEBI:138651;
CC         EC=2.3.1.184;
CC   -!- SIMILARITY: Belongs to the autoinducer synthase family.
