Accepted name: (R)-amidase
Reaction: (1) (R)-piperazine-2-carboxamide + H2O = (R)-piperazine-2-carboxylate + NH3
(2) β-alaninamide + H2O = β-alanine + NH3
Other name(s): R-stereospecific amidase; R-amidase
Systematic name: (R)-piperazine-2-carboxamide amidohydrolase
Comments: In addition (R)-piperidine-3-carboxamide is hydrolysed to (R)-piperidine-3-carboxylic acid and NH3, and (R)-N-tert-butylpiperazine-2-carboxamide is hydrolysed to (R)-piperazine-2-carboxylic acid and tert-butylamine with lower activity. The enzyme does not act on the other amide substrates which are hydrolysed by EC (amidase).
