CC -!- FUNCTION: Polyketide synthase; part of the Pks2 gene cluster that
CC mediates the formation of infectious structures (appressoria), enabling
CC these fungi to kill insects faster (Probable). The product of the Pks2
CC gene cluster is different from the one of Pks1 and has still not been
CC identified (Probable). {ECO:0000305|PubMed:29958281}.
CC -!- INDUCTION: Expression is up-regulated in appressoria-forming germlings
CC on locust cuticle. {ECO:0000269|PubMed:29958281}.
CC -!- DOMAIN: Multidomain protein; including a starter unit:ACP transacylase
CC (SAT) that selects the starter unit; a ketosynthase (KS) that catalyzes
CC repeated decarboxylative condensation to elongate the polyketide
CC backbone; a malonyl-CoA:ACP transacylase (MAT) that selects and
CC transfers the extender unit malonyl-CoA; a product template (PT) domain
CC that controls the immediate cyclization regioselectivity of the
CC reactive polyketide backbone; and an acyl-carrier protein (ACP) that
CC serves as the tether of the growing and completed polyketide via its
CC phosphopantetheinyl arm. {ECO:0000305|PubMed:29958281}.
CC -!- DOMAIN: The release of the polyketide chain from the non-reducing
CC polyketide synthase is mediated by the thioesterase (TE) domain
CC localized at the C-ter of the protein. {ECO:0000305|PubMed:29958281}.
