Chains	Enzyme Name	Description	Catalytic Residues
A	mannonate dehydratase M-CSA #960	Characterised enzymes in the mannonate dehydratase family (manD) catalyse the dehydration of mannonate to 2-dehydro-3-deoxy-D-gluconate, as part of the catabolism of D-glucuronate. Generally, genomes that encode a member of the mannonate dehydratase family do not have a UxuA (iron(II)-dependent mannoate dehydratase) homologue. Though UxuA also has the TIM barrel fold, it is not a member of the enolase superfamily. Thus, the enolase superfamily mannonate dehydratase family and the UxuAs are an example of convergent evolution of function.
