Protein

Acylamino-acid-releasing enzyme

Gene

APEH

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

This enzyme catalyzes the hydrolysis of the N-terminal peptide bond of an N-acetylated peptide to generate an N-acetylated amino acid and a peptide with a free N-terminus. It preferentially cleaves off Ac-Ala, Ac-Met and Ac-Ser.2 Publications

Catalytic activityi

Cleavage of an N-acetyl or N-formyl amino acid from the N-terminus of a polypeptide.
