Polyketide synthase; part of the Pks2 gene cluster that mediates the formation of infectious structures (appressoria), enabling these fungi to kill insects faster (PubMed:29958281). The product of the Pks2 gene cluster is different from the one of Pks1 and has still not been identified (PubMed:29958281). Expression is up-regulated in appressoria-forming germlings on locust cuticle (PubMed:26714892, PubMed:29958281). Expression is positively regulated by the Fus3 MAPK and negatively regulated by Opy2 (PubMed:29958281). Multidomain protein; including a starter unit:ACP transacylase (SAT) that selects the starter unit; a ketosynthase (KS) that catalyzes repeated decarboxylative condensation to elongate the polyketide backbone; a malonyl-CoA:ACP transacylase (MAT) that selects and transfers the extender unit malonyl-CoA; a product template (PT) domain that controls the immediate cyclization regioselectivity of the reactive polyketide backbone; and an acyl-carrier protein (ACP) that serves as the tether of the growing and completed polyketide via its phosphopantetheinyl arm. The release of the polyketide chain from the non-reducing polyketide synthase is mediated by the thioesterase (TE) domain localized at the C-ter of the protein. Does not affect conidial pigmentation.
