C-terminal domain in elongation

WebPolyketide synthases (PKSs) are a family of multi-domain enzymes or enzyme complexes that produce polyketides, a large class of secondary metabolites, in bacteria, fungi, plants, and a few animal lineages. The biosyntheses of polyketides share striking similarities with fatty acid biosynthesis.. The PKS genes for a certain polyketide are usually organized in … The C-terminal domain of some proteins has specialized functions. In humans, the CTD of RNA polymerase II typically consists of up to 52 repeats of the sequence Tyr-Ser-Pro-Thr-Ser-Pro-Ser. [1] This allows other proteins to bind to the C-terminal domain of RNA polymerase in order to activate polymerase activity.
