Polynucleotide adenylyltransferase

In enzymology, a polynucleotide adenylyltransferase (EC 2.7.7.19) is an enzyme that catalyzes the chemical reaction In enzymology, a polynucleotide adenylyltransferase (EC 2.7.7.19) is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are ATP and RNA, whereas its two products are pyrophosphate and RNA with an extra adenosine nucleotide at its 3' end. This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases). The systematic name of this enzyme class is ATP:polynucleotide adenylyltransferase.
