FunFam 151: DNA polymerase

There are 2 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.
 2 P26019 Q54SV8
Exodeoxyribonuclease I. [EC: 3.1.11.1]
Exonucleolytic cleavage in the 3'- to 5'-direction to yield nucleoside 5'-phosphates.
  • Preference for single-stranded DNA.
  • The Escherichia coli enzyme hydrolyzes glucosylated DNA.
  • Similar enzymes; mammalian DNase III, exonuclease IV, T2- and T4-induced exodeoxyribonucleases.
  • Formerly EC 3.1.4.25.
