1B65 - PubMed Abstract: 
The L-aminopeptidase D-Ala-esterase/amidase from Ochrobactrum anthropi (DmpA) releases the N-terminal L and/or D-Ala residues from peptide substrates. This is the only known enzyme to liberate N-terminal amino acids with both D and L stereospecificity. The DmpA active form is an alphabeta heterodimer, which results from a putative autocatalytic cleavage of an inactive precursor polypeptide.
