FunFam 47508: Replication factor C large subunit

There are 3 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
DNA-directed DNA polymerase. [EC: 2.7.7.7]
Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).
  • Catalyzes DNA-template-directed extension of the 3'-end of a DNA strand by one nucleotide at a time.
  • Cannot initiate a chain de novo.
  • Requires a primer which may be DNA or RNA.
  • See also EC 2.7.7.49.
 7 A0A087RZ30 A0A087S510 A0A0G0R4P0 A0A0N9YYF9 A0A1M4MJJ1 B7IDS2 K2PFZ8
Endopeptidase La. [EC: 3.4.21.53]
Hydrolysis of proteins in presence of ATP.
  • ATP hydrolysis is linked with peptide bond hydrolysis.
  • Vanadate inhibits both reactions.
  • A similar enzyme occurs in animal mitochondria.
  • Belongs to peptidase family S16.
 1 B0EMT0
DNA ligase (NAD(+)). [EC: 6.5.1.2]
NAD(+) + (deoxyribonucleotide)(n)-3'-hydroxyl + 5'-phospho- (deoxyribonucleotide)(m) = (deoxyribonucleotide)(n+m) + AMP + beta- nicotinamide D-nucleotide.
  • The enzyme, typically found in bacteria, catalyzes the ligation of DNA strands with 3'-hydroxyl and 5'-phosphate termini, forming a phosphodiester and sealing certain types of single-strand breaks in duplex DNA.
  • Catalysis occurs by a three-step mechanism, starting with the activation of the enzyme by NAD(+), forming a phosphoramide bond between adenylate and a lysine residue.
  • The adenylate group is then transferred to the 5'-phosphate terminus of the substrate, forming the capped structure 5'-(5'-diphosphoadenosine)-(DNA).
  • Finally, the enzyme catalyzes a nucleophilic attack of the 3'-OH terminus on the capped terminus, which results in formation of the phosphodiester bond and release of the adenylate.
  • RNA can also act as substrate, to some extent.
  • Cf. EC 6.5.1.1, EC 6.5.1.6, and EC 6.5.1.7.
