Chains	Enzyme Name	Description	Catalytic Residues
A	L-rhamnose isomerase M-CSA #488	This enzyme interconverts L-rhamnose and L-rhamnulose. In some species, including Escherichia coli, this is the first step in rhamnose catabolism. The enzyme contains two divalent metal ions located at different metal-binding sites within the active site. The enzyme binds the closed ring form of the substrate and catalyses ring opening to generate a form of open-chain conformation that is coordinated to one of the metal sites.
