(GenBank) Prephenate dehydratase (|NP_628146.1| prephenate dehydratase [Streptomyces coelicolor A3(2)]; ZP_00058942.1| COG0077: Prephenate dehydratase [Thermobifida fusca]). pfam00800, PDT, Prephenate dehydratase. This protein is involved in Phenylalanine biosynthesis. This protein catalyses the decarboxylation of prephenate to phenylpyruvate. pfam01842, ACT, ACT domain. This family of domains generally have a regulatory role. ACT domains are linked to a wide range of metabolic enzymes that are regulated by amino acid concentration. Pairs of ACT domains bind specifically to a particular amino acid leading to regulation of the linked enzyme.; High confidence in function and specificity
