FunFam 3155: Endonuclease yncB domain protein

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
Micrococcal nuclease. [EC: 3.1.31.1]
Endonucleolytic cleavage to nucleoside 3'-phosphates and 3'-phosphooligonucleotide end-products.
  • Hydrolyzes double- or single-stranded substrate.
  • Similar enzymes: Chlamydomonas nuclease, spleen phosphodiesterase, spleen endonuclease.
  • Formerly EC 3.1.4.7.

5'-nucleotidase. [EC: 3.1.3.5]
A 5'-ribonucleotide + H(2)O = a ribonucleoside + phosphate.
  • Wide specificity for 5'-nucleotides.

2',3'-cyclic-nucleotide 2'-phosphodiesterase. [EC: 3.1.4.16]
Nucleoside 2',3'-cyclic phosphate + H(2)O = nucleoside 3'-phosphate.
  • Also hydrolyzes 3'-nucleoside monophosphates and bis-4-nitrophenyl phosphate, but not 3'-deoxynucleotides.
  • Similar reactions are carried out by EC 3.1.27.3 and EC 3.1.27.5.
