| catalytic Activity | CATALYTIC ACTIVITY: Reaction=Dipeptidase E catalyzes 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.; EC=3.4.13.21; Evidence={ECO:0000255|HAMAP-Rule:MF_00510}; |
| DNA Binding | |
| EC Number | 3.4.13.21 |
| Enzyme Function | FUNCTION: Hydrolyzes dipeptides containing N-terminal aspartate residues. May play a role in allowing the cell to use peptide aspartate to spare carbon otherwise required for the synthesis of the aspartate family of amino acids. {ECO:0000255|HAMAP-Rule:MF_00510}. |
