Abstract excerpt
Streptolydigin is a tetramic acid antibiotic produced by Streptomyces lydicus NRRL 2433 and involving a hybrid polyketide synthase (PKS)-nonribosomal peptide synthetase (NRPS) system in its biosynthesis. The streptolydigin amino-acid precursor, 3-methylaspartate, has been proposed to be condensed to the polyketide portion of the molecule by a NRPS composed by three enzymes (SlgN1, SlgN2 and SlgL). On the other...
