Enzyme Information

5.3.1.14
L-rhamnose isomerase.
based on mapping to UniProt Q9KCL9
L-rhamnopyranose = L-rhamnulose.
-!- 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.
