Chains	Enzyme Name	Description	Catalytic Residues
A	L-fuconate dehydratase M-CSA #961	L-fuconate dehydratase is a member of the enolase superfamily and is known to play a role in the catabolism of L-fucose. It catalyses the dehydration of L-fuconate to 2-keto-3-deoxy-L-fuconate by the abstraction of the proton alpha to the carboxylate group of the substrate to generate an enediolate intermediate that is stabilised by an essential magnesium ion.
