In enzymology, a polynucleotide adenylyltransferase (EC 2.7.7.19) is an enzyme that catalyzes the chemical reaction
- ATP + RNA-3'OH pyrophosphate + RNApA-3'OH

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.
Human genes with this activity include TUT1, MTPAP, PAPOLA, PAPOLB, PAPOLG, TENT2, TENT4A, TENT4B, TENT5C, TENT5D.
