Scytalone dehydratase-like protein; 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). Homotrimer. Each subunit contains an active site, located in the central part of the hydrophobic core of the monomer, which functions independently. Belongs to the scytalone dehydratase family.
