|Name||RNA ligase T4|
|Cat. #||E349||E350 |
|Package, u.a.||1000||5000 |
|Concentration, u.a./ml||10000||10000 |
|Source||Isolated from E.coli strain that carries the cloned RNA ligase gene from bacteriophage T4|
|Description||RNA Ligase catalyzes ligation of a 5` phosphoryl - terminated nucleic acid donor to a 3` hydroxyl - terminated nucleic acid acceptor through the formation of a 3` -> 5` phosphodiester bond, with hydrolysis of ATP to AMP and PPi. Substrates include single-stranded RNA and DNA as well as dinucleoside pyrophosphates. |
- labeling of 3`-termini of RNA with 5` - [32P] pCp;
- inter- and intra-molecular joining of RNA and DNA molecules.
