cleaves beta- and mixed alpha,beta-peptides and amides, but a short side chain of the N-terminal beta-amino acid residue seems to be a prerequisite, since only peptides carrying N-terminal betahGly and betahAla are hydrolyzed with good efficiencies. Tripeptides carrying two consecutive N-terminal beta-homoamino acids as well as peptides with alpha-amino acids in the N-terminal position do not serve as substrates for DmpA
