DOI: 10.1021/acs.jafc.1c00771

Abstract: Polyketide synthase-terpenoid synthase (PKS-TPS) hybrid pathways for biosynthesis of unique sesquiterpenyl epoxy-cyclohexenoids (SECs) have been found to be widely distributed in plant pathogenic fungi. However, the natural and ecological functions of these pathways and their… read more here.

DOI: 10.1021/acs.orglett.1c04189

Abstract: The heterologous expression of a nonreducing polyketide synthase gene oesA from Penicillium crustosum led to the identification of orsellinoylpropanoic acid (1). Domain deletion and recombination proved that OesA catalyzes not only the formation of orsellinic… read more here.

DOI: 10.1021/acs.orglett.3c00103

Abstract: A cryptic tetronate biosynthetic pathway was identified in Kitasatospora niigatensis DSM 44781 via heterologous expression. Distinct from the currently known biosynthetic pathways, this system utilizes a partially functional nonribosomal peptide synthetase and a broadly selective… read more here.

DOI: 10.1021/acs.orglett.4c01039

Abstract: Guided by the retrobiosynthesis hypothesis, we characterized a fungal polyketide synthase-nonribosomal peptide synthetase (PKS-NRPS) hybrid megasynthetase pathway to generate 2-trans-4-trans-2-methylsorbyl-d-leucine (1), a polyketide amino acid conjugate that inhibits Arabidopsis root growth. The biosynthesis of 1… read more here.
