This entry contains members such as the arylmalonate decarboxylases (AMDase; EC 4.1.1.76), which belong to the family of carboxy-lyases (EC 4.1). Amdases are capable of decarboxylating a range of alpha-disubstituted malonic acid derivates to enantiopure products without the need for any cofactor. AMDases are members of the widespread Asp/Glu racemase family Pfam:PF01177 together with aspartate (EC 5.1.1.13) and glutamate racemases (EC 5.1.1.3), hydantoin racemases (EC 5.1.99.5) and maleate isomerases (EC 5.2.1.1) [1].
