CC -!- FUNCTION: Polyketide synthase; part of the Pks1 gene cluster that
CC mediates the biosynthesis of an anthraquinone derivative pigment that
CC contributes to conidial pigmentation that provides protection from UV
CC radiation, heat and cold stress (PubMed:29958281). The polyketide
CC synthase Pks1 produces 1-acetyl-2,4,6,8-tetrahydroxy-9,10-anthraquinone
CC though condensation of acetyl-CoA with malonyl-CoA (By similarity). The
CC dehydratase EthD and the laccase Mlac1 further convert the
CC anthraquinone derivative into the final conidial pigment
CC (PubMed:20382249). {ECO:0000250|UniProtKB:E9F646,
CC ECO:0000269|PubMed:20382249, ECO:0000269|PubMed:29958281}.
CC -!- INDUCTION: Highly expressed during conidiation (PubMed:29958281). A
CC conserved conidiation regulatory pathway containing BrlA, AbaA and WetA
CC regulates expression. During conidiation BlrA up-regulates AbaA, which
CC in turn controls WetA. Moreover, the Hog1 MAPK regulates fungal
CC conidiation by controlling the conidiation regulatory pathway, and that
CC all three pigmentation genes Pks1, EthD and Mlac1 exercise feedback
CC regulation of conidiation (By similarity).
CC {ECO:0000250|UniProtKB:E9F646, 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}.
CC -!- DISRUPTION PHENOTYPE: Results in red conidia.
CC {ECO:0000269|PubMed:29958281}.
