T4 RNA Ligase 1 (ssRNA Ligase)
T4 RNA Ligase 1 (ssRNA Ligase)

T4 RNA Ligase 1 catalyzes the 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.

Description:
T4 RNA Ligase 1 catalyzes the 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.

Applications:

  • Labeling of 3'-termini of RNA with 5'-[32P] pCp
  • Inter- and intramolecular joining of RNA and DNA molecules
  • Synthesis of single-stranded oligodeoxyribo-nucleotides
  • Incorporation of unnatural amino acids into proteins
  • Ligation of ssRNA and DNA

Source:
An E. coli strain that carries the T4 RNA Ligase 1 gene
