A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 1.1.3.28

Accepted Name
Nucleoside oxidase.
Reaction catalysed
Inosine + O(2) <=> 9-riburonosylhypoxanthine + 2 H(2)O
Comment(s)
  • Other purine and pyrimidine nucleosides (as well as 2'-deoxyribonucleosides) are substrates, but ribose and nucleotides are not substrates.
  • The overall reaction takes place in two separate steps, with the 5'-dehydro nucleoside being released from the enzyme to serve as substrate for the second reaction.
  • Differs from EC 1.1.3.39 as it produces water rather than hydrogen peroxide.
