Biosynthesis of carbapenem antibiotic and prodigiosin pigment in Serratia is under quorum sensing control
Abstract
Serratia sp. ATCC 39006 produces the carbapenem antibiotic, carbapen‐2‐em‐3‐carboxylic acid and the red pigment, prodigiosin. We have previously reported the characterization of a gene, carR, controlling production of carbapenem in this strain. We now describe further characterization of the carR locus to locate the genes encoding carbapenem biosynthetic and resistance functions. A novel family of diverse proteins showing sequence similarity to the C‐terminal domain of CarF (required for carbapenem resistance) is described. We also report the isolation of the locus involved in the biosynthesis of the red pigment, prodigiosin. A cosmid containing ≈ 35 kb of the Serratia chromosome encodes synthesis of the pigment in the heterologous host, Erwinia carotovora, demonstrating, for the first time, that the complete prodigiosin biosynthetic gene cluster had been cloned and functionally expressed. We report the isolation of a third locus in Serratia, containing convergently transcribed genes, smaI and smaR, encoding LuxI and LuxR homologues respectively. SmaI directs the synthesis of N‐acyl homoserine lactones involved in the quorum sensing process. We demonstrate that biosynthesis of the two secondary metabolites, carbapenem antibiotic and prodigiosin pigment, is under pheromone‐mediated transcriptional regulation in this bacterium. Finally, we describe a new prodigiosin‐based bioassay for detection of some N‐acyl homoserine lactones.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
