Protein

Peptidase E

Gene
pepE, b4021, JW3981
Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

Functioni

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 By similarity.UniRule annotation

Catalytic activityi

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.UniRule annotation
