CC -!- FUNCTION: Highly reducing polyketide synthase; part of the gene cluster
CC that mediates the biosynthesis of the lipopeptide fusaristatin A
CC (PubMed:25412204). Fusaristatin A consists of a polyketide chain linked
CC to three amino acid residues glutamine (Gln), dehydroalanine (dehydro-
CC Ala), and beta-aminoisobutyric acid (PubMed:25412204). The biosynthesis
CC starts with formation of a linear polyketide chain by the highly
CC reducing polyketide synthase PKS6 (PubMed:25412204). The gene cluster
CC does not contain an acyl-CoA ligase or an acyl-transferase, and it is
CC therefore predicted that the polyketide is transferred directly to the
CC nonribosomal peptide synthetase NRPS7 (Probable). Modules 1-3 from
CC NRPS7 incorporate dehydro-Ala, Gln, and beta-aminoisobutyric acid in
CC the compound, which is released by cyclization (PubMed:25412204). The
CC beta-aminoisobutyric acid units are most likely not freely available to
CC the NRPS, but can be synthesized from thymine, which requires a
CC dehydrogenase, a monooxygenase, and an aminotransferase. The
CC fusaristatin A cluster contains a cytochrome P450 monooxygenase
CC (FGSG_08207) and an aminotransferase (FGSG_17085), which theoretically
CC can perform two of the enzymatic steps (Probable). The enzymes may
CC however also be involved in biosynthesis of dehydroalanine or
CC modification of the polyketide (Probable). The dehydro-Ala residue can
CC be a result of cyclization, where serine is dehydrated (Probable). The
CC last gene of the cluster encodes a protein with an A/B barrel domain
CC found in variable enzymes, which hampers functional prediction
CC (Probable). {ECO:0000269|PubMed:25412204, ECO:0000305|PubMed:25412204}.
CC -!- PATHWAY: Secondary metabolite biosynthesis.
CC {ECO:0000269|PubMed:25412204}.
CC -!- DOMAIN: Multidomain protein; including a ketosynthase (KS) that
CC catalyzes repeated decarboxylative condensation to elongate the
CC polyketide backbone; a malonyl-CoA:ACP transacylase (MAT) that selects
CC and transfers the extender unit malonyl-CoA; a dehydratase (DH) domain
CC that reduces hydroxyl groups to enoyl groups; a methyltransferase
CC (CMeT) domain responsible for the incorporation of methyl groups; an
CC enoylreductase (ER) domain that reduces enoyl groups to alkyl group; a
CC ketoreductase (KR) domain that catalyzes beta-ketoreduction steps; and
CC an acyl-carrier protein (ACP) that serves as the tether of the growing
CC and completed polyketide via its phosphopantetheinyl arm.
CC {ECO:0000305|PubMed:25412204}.
CC -!- DISRUPTION PHENOTYPE: impairs the production of fusaristatin A.
CC {ECO:0000269|PubMed:25412204}.
