Abstract
Type II polyketide synthases (PKSs) normally synthesize polycyclic aromatic compounds in nature, and the potential to elaborate further diverse skeletons was recently revealed by the discovery of a polyene subgroup. Here, we show a type II PKS machinery for the biosynthesis of a five-membered nonaromatic skeleton contained in the nonproteinogenic amino acid cispentacin and the plant toxin coronatine. We successfully produce cispentacin in a heterologous host and reconstruct its biosynthesis using seven recombinant proteins in vitro. Biochemical analyses of each protein reveal the unique enzymatic reactions, indicating that a heterodimer of type II PKS-like enzymes (AmcF-AmcG) catalyzes a single C2 elongation as well as a subsequent cyclization on the acyl carrier protein (AmcB) to form a key intermediate with a five-membered ring. The subsequent reactions, which are catalyzed by a collection of type II PKS-like enzymes, are also peculiar. This work further expands the definition of type II PKS and illuminates an unexplored genetic resource for natural products.

Coronatine Gene Expression In Vitro and In Planta, and Protein Accumulation During Temperature Downshift in Pseudomonas syringae. SENSORS 2009; 9:4272-85. [PMID: 22408526 PMCID: PMC3291911 DOI: 10.3390/s90604272] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/01/2009] [Revised: 05/22/2009] [Accepted: 05/26/2009] [Indexed: 11/30/2022]
Abstract
The plant pathogenic bacterium Pseudomonas syringae PG4180 synthesizes high levels of the phytotoxin coronatine (COR) at the virulence-promoting temperature of 18 °C, but negligible amounts at 28 °C. Temperature-dependent COR gene expression is regulated by a modified two-component system, consisting of a response regulator, CorR, the histidine protein kinase CorS, and a third component, termed CorP. We analyzed at transcriptional and translational levels the expression of corS and the cma operon involved in COR biosynthesis after a temperature downshift from 28 to 18 °C. Expression of cma was induced within 20 min and increased steadily whereas corS expression was only slightly temperature-dependent. Accumulation of CmaB correlated with accumulation of cma mRNA. However, cma transcription was suppressed by inhibition of de novo protein biosynthesis. A transcriptional fusion of the cma promoter to a promoterless egfp gene was used to monitor the cma expression in vitro and in planta. A steady induction of cma::egfp by temperature downshift was observed in both environments. The results indicate that PG4180 responds to a temperature decrease with COR gene expression. However, COR gene expression and protein biosynthesis increased steadily, possibly reflecting adaptation to long-term rather than rapid temperature changes.

Abstract
The 4'-phosphopantetheinyl transferases (PPTases) catalyze the transfer of a 4'-phosphopantetheine moiety from coenzyme A to phosphopantetheine-dependent carrier proteins. The carrier proteins (CPs) are required for the biosynthesis of peptides synthesized by nonribosomal peptide synthases and the biosynthesis of fatty acids and polyketides. A single PPTase (PcpS) is present in the pathogenic bacterium Pseudomonas aeruginosa. Several pathovars of Pseudomonas syringae produce the chlorosis-inducing phytotoxin coronatine. Structural genes for coronatine biosynthesis include two ACPs, two ACP domains, and one peptidyl carrier protein (PCP) domain. To gain insight into factors affecting coronatine biosynthesis, the PPTase of P. syringae pv. syringae FF5 has been investigated. A single PPTase gene (pspT) was amplified from this organism by PCR. The translation product PspT exhibited 62% identity to PcpS as well as higher levels of identity to other, uncharacterized Pseudomonad PPTases. PspT was overproduced in soluble form in Escherichia coli and its enzymatic properties were compared with those of PcpS. PspT exhibited broad substrate specificity, and it displayed the highest activity with a PCP domain. In contrast, the most efficient substrates for PcpS are CPs from primary metabolism. These results indicate phosphopantetheinyl transferases from different Pseudomonas sp. may vary significantly in their enzymatic properties.
