IntEnz Enzyme Nomenclature
EC 3.2.2.8

Names

Accepted name:
ribosylpyrimidine nucleosidase
Other names:
N-ribosylpyrimidine nucleosidase
N-ribosylpyrimidine ribohydrolase
pyrimidine nucleosidase
RihB
YeiK
nucleoside ribohydrolase
Systematic name:
pyrimidine-nucleoside ribohydrolase

Reaction

Comments:

Also hydrolyses purine D-ribonucleosides, but more slowly. 2'-, 3'- and 5'-deoxynucleosides are not substrates [3].
