Biosynthesis of the red antibiotic, prodigiosin, in Serratia: identification of a novel 2-methyl-3-n-amyl-pyrrole (MAP) assembly pathway, definition of the terminal condensing enzyme, and implications for undecylprodigiosin biosynthesis in Streptomyces.
Williamson N.R., Simonsen H.T., Ahmed R.A., Goldet G., Slater H., Woodley L., Leeper F.J., Salmond G.P.
The biosynthetic pathway of the red-pigmented antibiotic, prodigiosin, produced by Serratia sp. is known to involve separate pathways for the production of the monopyrrole, 2-methyl-3-n-amyl-pyrrole (MAP) and the bipyrrole, 4-methoxy-2,2'-bipyrrole-5-carbaldehyde (MBC) which are then coupled in th ... >> More
The biosynthetic pathway of the red-pigmented antibiotic, prodigiosin, produced by Serratia sp. is known to involve separate pathways for the production of the monopyrrole, 2-methyl-3-n-amyl-pyrrole (MAP) and the bipyrrole, 4-methoxy-2,2'-bipyrrole-5-carbaldehyde (MBC) which are then coupled in the final condensation step. We have previously reported the cloning, sequencing and heterologous expression of the pig cluster responsible for prodigiosin biosynthesis in two Serratia sp. In this article we report the creation of in-frame deletions or insertions in every biosynthetic gene in the cluster from Serratia sp. ATCC 39006. The biosynthetic intermediates accumulating in each mutant have been analysed by LC-MS, cross-feeding and genetic complementation studies. Based on these results we assign specific roles in the biosynthesis of MBC to the following Pig proteins: PigI, PigG, PigA, PigJ, PigH, PigM, PigF and PigN. We report a novel pathway for the biosynthesis of MAP, involving PigD, PigE and PigB. We also report a new chemical synthesis of MAP and one of its precursors, 3-acetyloctanal. Finally, we identify the condensing enzyme as PigC. We reassess the existing literature and discuss the significance of the results for the biosynthesis of undecylprodigiosin by the Red cluster in Streptomyces coelicolor A3(2). << Less

Conversion of L-proline to pyrrolyl-2-carboxyl-S-PCP during undecylprodigiosin and pyoluteorin biosynthesis.
Thomas M.G., Burkart M.D., Walsh C.T.
Several medically and agriculturally important natural products contain pyrrole moieties. Precursor labeling studies of some of these natural products have shown that L-proline can serve as the biosynthetic precursor for these moieties, including those found in coumermycin A(1), pyoluteorin, and o ... >> More
Several medically and agriculturally important natural products contain pyrrole moieties. Precursor labeling studies of some of these natural products have shown that L-proline can serve as the biosynthetic precursor for these moieties, including those found in coumermycin A(1), pyoluteorin, and one of the pyrroles of undecylprodigiosin. This suggests a novel mechanism for pyrrole biosynthesis. The biosynthetic gene clusters for these three natural products each encode proteins homologous to adenylation (A) and peptidyl carrier protein (PCP) domains of nonribosomal peptide synthetases in addition to novel acyl-CoA dehydrogenases. Here we show that the three proteins from the undecylprodigiosin and pyoluteorin biosynthetic pathways are sufficient for the conversion of L-proline to pyrrolyl-2-carboxyl-S-PCP. This establishes a novel mechanism for pyrrole biosynthesis and extends the hypothesis that organisms use A/PCP pairs to partition an amino acid into secondary metabolism. << Less

The Serratia gene cluster encoding biosynthesis of the red antibiotic, prodigiosin, shows species- and strain-dependent genome context variation.
Harris A.K., Williamson N.R., Slater H., Cox A., Abbasi S., Foulds I., Simonsen H.T., Leeper F.J., Salmond G.P.
The prodigiosin biosynthesis gene cluster (pig cluster) from two strains of Serratia (S. marcescens ATCC 274 and Serratia sp. ATCC 39006) has been cloned, sequenced and expressed in heterologous hosts. Sequence analysis of the respective pig clusters revealed 14 ORFs in S. marcescens ATCC 274 and ... >> More
The prodigiosin biosynthesis gene cluster (pig cluster) from two strains of Serratia (S. marcescens ATCC 274 and Serratia sp. ATCC 39006) has been cloned, sequenced and expressed in heterologous hosts. Sequence analysis of the respective pig clusters revealed 14 ORFs in S. marcescens ATCC 274 and 15 ORFs in Serratia sp. ATCC 39006. In each Serratia species, predicted gene products showed similarity to polyketide synthases (PKSs), non-ribosomal peptide synthases (NRPSs) and the Red proteins of Streptomyces coelicolor A3(2). Comparisons between the two Serratia pig clusters and the red cluster from Str. coelicolor A3(2) revealed some important differences. A modified scheme for the biosynthesis of prodigiosin, based on the pathway recently suggested for the synthesis of undecylprodigiosin, is proposed. The distribution of the pig cluster within several Serratia sp. isolates is demonstrated and the presence of cryptic clusters in some strains shown. The pig cluster of Serratia marcescens ATCC 274 is flanked by cueR and copA homologues and this configuration is demonstrated in several S. marcescens strains, whilst these genes are contiguous in strains lacking the pig cluster. << Less
