Chains	Enzyme Name	Description	Catalytic Residues
A	methylmalonyl-CoA decarboxylase M-CSA #70	Methylmalonyl-CoA decarboxylase (MMCD) is a member of the cronotase super family, a collection of enzymes characterised by the presence of oxy anion intermediates or transition states with a significant localisation of negative charge in their reactions. The breadth of catalytic action within this family is demonstrated by the spread of associated enzymes across all six of the Enzyme Commission classes.
