Dipeptidase E (EC 3.4.13.21, aspartyl dipeptidase, peptidase E, PepE gene product (Salmonella typhimurium)) is an enzyme.[1][2] This enzyme catalyses the following chemical reaction
- 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.
