FunFam 2068: DNA polymerase I PolA

There are 4 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.

Anaerobic carbon-monoxide dehydrogenase. [EC: 1.2.7.4]
CO + H(2)O + 2 oxidized ferredoxin = CO(2) + 2 reduced ferredoxin + 2 H(+).
  • This prokaryotic enzyme catalyzes the reversible reduction of CO(2) to CO.
  • The electrons are transferred to redox proteins such as ferredoxin.
  • In purple sulfur bacteria and methanogenic archaea it catalyzes the oxidation of CO to CO(2), which is incorporated by the Calvin-Benson- Basham cycle or released, respectively.
  • In acetogenic and sulfate-reducing microbes it catalyzes the reduction of CO(2) to CO, which is incorporated into acetyl CoA by EC 2.3.1.169, with which the enzyme forms a tight complex in those organisms.
  • In purple sulfur bacteria the enzyme forms complexes with the Ni-Fe-S protein EC 1.12.7.2 which catalyze the overall reaction: CO + H(2)O = CO(2) + H(2).
  • Cf. EC 1.2.5.3.
  • Formerly EC 1.2.99.2.
 5 A0A1B3RWH2 C0RGI4 C4IP22 C4WGU1 M5JRF6
Exodeoxyribonuclease (lambda-induced). [EC: 3.1.11.3]
Exonucleolytic cleavage in the 5'- to 3'-direction to yield nucleoside 5'-phosphates.
  • Preference for double-stranded DNA.
  • Does not attack single-strand breaks.
  • Similar enzymes: T4, T5 and T7 exonucleases, mammalian DNase IV.
  • Formerly EC 3.1.4.28.
 1 Q3IJF9
N-acetylmuramoyl-L-alanine amidase. [EC: 3.5.1.28]
Hydrolyzes the link between N-acetylmuramoyl residues and L-amino acid residues in certain cell-wall glycopeptides.
  • Formerly EC 3.4.12.5, EC 3.4.17.7 and EC 3.4.19.10.
