Multiple mutations in polyketide synthase led to disruption of Psittacofulvin production across diverse parrot species
Abstract Polyketide synthases (PKSs) are crucial multidomain enzymes in diverse natural product biosynthesis.Parrots use a type I PKS to produce a unique pigment called psittacofulvin in their feathers.In domesticated budgerigars and lovebirds, the same amino acid substitution (R644W) within malonyl/acetyltransferase (MAT) domain of this enzyme has
