This protein enables 5 target(s):

Target	Category	Definition
aminopeptidase activity	molecular function	Catalysis of the hydrolysis of a single N-terminal amino acid residue from a polypeptide chain. [https://www.ebi.ac.uk/merops/about/glossary.shtml#AMINOPEPTIDASE, PMID:24157837]
epoxide hydrolase activity	molecular function	Catalysis of the reaction: an epoxide + H2O = an ethanediol. [EC:3.3.2.10]
metalloexopeptidase activity	molecular function	Catalysis of the hydrolysis of a peptide bond not more than three residues from the N- or C-terminus of a polypeptide chain by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions. [GOC:mah, https://www.ebi.ac.uk/merops/about/glossary.shtml]
zinc ion binding	molecular function	Binding to a zinc ion (Zn). [GOC:ai]
metalloaminopeptidase activity	molecular function	Catalysis of the hydrolysis of a single N-terminal amino acid residue from a polypeptide chain by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions.

This protein is located in 3 target(s):

Target	Category	Definition
extracellular region	cellular component	The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. [GOC:go_curators]
plasma membrane	cellular component	The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363]
extracellular exosome	cellular component	A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.

This protein is active in 1 target(s):

Target	Category	Definition
extracellular space	cellular component	That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid. [ISBN:0198547684]

This protein is involved in 1 target(s):

Target	Category	Definition
proteolysis	biological process	The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds. [GOC:bf, GOC:mah]
