Chains	Enzyme Name	Description	Catalytic Residues
A	dipeptidase E M-CSA #599	Aspartyl peptidase has unique substrate specificity for Asp-Xaa dipeptides and Asp-Gly-Gly tripeptide. Not classified in any known peptidase family. Convergent evolution accounts for catalytic triad His157, Ser120, Glu192. Found in bacteria and recently found to be present in isolated eukaryotes. This protein is a member of the MEROPS peptidase family S51 (dipeptidase E, clan PC).
