In enzymology, a polynucleotide adenylyltransferase () 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. ==Naming== 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. Other names in common use include: * NTP polymerase * RNA adenylating enzyme * AMP polynucleotidylexotransferase * ATP-polynucleotide adenylyltransferase * ATP:polynucleotidylexotransferase * Poly(A) polymerase * Poly(A) synthetase * Polyadenylate nucleotidyltransferase * Polyadenylate polymerase * Polyadenylate synthetase * Polyadenylic acid polymerase * Polyadenylic polymerase * Terminal riboadenylate transferase * Poly(A) hydrolase * RNA formation factors * PF1 * Adenosine triphosphate:ribonucleic acid adenylyltransferase 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「polynucleotide adenylyltransferase」の詳細全文を読む スポンサード リンク
