RNA ligase (ATP)


In enzymology, an RNA ligase is an enzyme that catalyzes the chemical reaction
The 3 substrates of this enzyme are ATP, n, and m, whereas its 3 products are AMP, diphosphate, and n+m.
This enzyme belongs to the family of ligases, specifically those forming phosphoric-ester bonds. The systematic name of this enzyme class is poly:poly ligase . Other names in common use include polyribonucleotide synthase , RNA ligase, polyribonucleotide ligase, and ribonucleic ligase.

Structural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and.
