CC   -!- FUNCTION: Hydrolyzes dipeptides containing N-terminal aspartate
CC       residues. May play a role in allowing the cell to use peptide aspartate
CC       to spare carbon otherwise required for the synthesis of the aspartate
CC       family of amino acids. {ECO:0000255|HAMAP-Rule:MF_00510}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Dipeptidase E catalyzes the hydrolysis of dipeptides Asp-|-
CC         Xaa. It does not act on peptides with N-terminal Glu, Asn or Gln, nor
CC         does it cleave isoaspartyl peptides.; EC=3.4.13.21;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00510};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00510}.
CC   -!- SIMILARITY: Belongs to the peptidase S51 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00510}.
