Enzyme Information
| 2.7.7.19 |
Polynucleotide adenylyltransferase.
based on mapping to UniProt O13833
ATP + RNA(n) = diphosphate + RNA(n+1).
-!- 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.
|
| 2.7.7.52 |
RNA uridylyltransferase.
based on mapping to UniProt O13833
UTP + RNA(n) = diphosphate + RNA(n+1).
-!- Requires an oligoribonucleotide or polyribonucleotide with a free terminal 3'-OH as a primer.
