dipeptidase E catalyses the hydrolysis of dipeptides Asp-/-Xaa. It does not act on peptides with N-terminal Glu, Asn or Gln, nor does it cleave isoaspartyl peptides
A free carboxy group is not absolutely required in the substrate since Asp-Phe-NH2 and Asp-Phe-OMe are hydrolysed somewhat more slowly than dipeptides with free C-termini. No peptide larger than a C-blocked dipeptide is known to be a substrate. Asp-NH-Np is hydrolysed and is a convenient substrate for routine assay. The enzyme is most active near pH 7.0, and is not inhibited by di-isopropylfluorophosphate or phenylmethanesulfonyl fluoride. Belongs in peptidase family S51
