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 5.3.1.14

Accepted Name
L-rhamnose isomerase.
Alternative Name(s)
Rhamnose isomerase.
Reaction catalysed
L-rhamnopyranose <=> L-rhamnulose
Cofactor(s)
Divalent cation.
Comment(s)
  • The enzyme binds the closed ring form of the substrate and catalyzes ring opening to generate a form of open-chain conformation that is coordinated to one of the metal sites.
  • Isomerization proceeds via a hydride-shift mechanism.
  • While the enzyme from the bacterium Escherichia coli is specific for L-rhamnose, the enzyme from the bacterium Pseudomonas stutzeri has broad substrate specificity and catalyzes the interconversion of L-mannose and L-fructose, L-lyxose and L-xylulose, D-ribose and D-ribulose, and D-allose and D-psicose.
