A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 2.7.7.19

Accepted Name
Polynucleotide adenylyltransferase.
Alternative Name(s)
NTP polymerase.
Poly(A) polymerase.
RNA adenylating enzyme.
Reaction catalysed
ATP + RNA(n) <=> diphosphate + RNA(n+1)
Comment(s)
  • Also acts slowly with CTP.
  • Catalyzes template-independent extension of the 3'-end of a DNA strand by one nucleotide at a time.
  • Cannot initiate a chain de novo.
  • The primer, depending on the source of the enzyme, may be an RNA or DNA fragment or oligo(A) bearing a 3'-OH terminal group.
  • See also EC 2.7.7.6.
