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 4.2.3.124

Accepted Name
2-deoxy-scyllo-inosose synthase.
Reaction catalysed
D-glucose-6-phosphate <=> 2-deoxy-L-scyllo-inosose + phosphate
Cofactor(s)
Cobalt cation.
Comment(s)
  • Involved in the biosynthetic pathways of several clinically important aminocyclitol antibiotics, including kanamycin, butirosin, neomycin and ribostamycin.
  • Requires an NAD(+) cofactor, which is transiently reduced during the reaction.
  • The enzyme from the bacterium Bacillus circulans forms a complex with the glutamine amidotransferase subunit of pyridoxal 5'-phosphate synthase (EC 4.3.3.6), which appears to stabilize the complex.
