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.
