Poly(A) Polymerase, Yeast catalyzes the template-independent addition of adenosine residues to the 3’ ends of RNA molecules using ATP as a substrate to create a poly(A) tail. When cordycepin-5'-triphosphate (3’-dATP) is substituted for ATP, the enzyme adds a single dA residue to the 3’-terminus of RNA. Neither ADP nor dATP can be used as substrates for this enzyme. Poly(A) Polymerase from yeast is particularly effective for oligonucleotide-labeling and poly(A) tailing of long RNA templates, making it a superior choice compared to E. coli-derived enzymes. This enzyme is ideal for applications that require precise polyadenylation, such as RNA sequencing and cDNA synthesis.

Poly(A) Polymerase adds adenosine residues in a template-independent manner to the 3′-OH end of single-stranded RNA, preferring single-stranded RNA substrates. It requires ATP and Mg²⁺ for activity and is used for 3′-end labeling, poly(A) tailing for in vitro translation, and RNA detection assays.
