FunFam 25: Probable ribonucleoside hydrolase

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
Ribosylpyrimidine nucleosidase. [EC: 3.2.2.8]
A pyrimidine nucleoside + H(2)O = D-ribose + a pyrimidine base.
  • Also hydrolyzes purine D-ribonucleosides, more slowly.
  • 2'-, 3'- and 5'-deoxynucleosides are not substrates.

Purine nucleosidase. [EC: 3.2.2.1]
A purine nucleoside + H(2)O = D-ribose + a purine base.
  • The enzyme from the bacterium Ochrobactrum anthropi specifically catalyzes the irreversible N-riboside hydrolysis of purine nucleosides.
  • Pyrimidine nucleosides, purine and pyrimidine nucleotides, NAD(+), NADP(+) and nicotinaminde mononucleotide are not substrates.
