Subcellular location

Subcellular Location:
Secreted, extracellular space.

Function

Function:
Catalyzes the degradation of compounds such as putrescine, histamine, spermine, and spermidine, substances involved in allergic and immune responses, cell proliferation, tissue differentiation, tumor formation, and possibly apoptosis. Placental DAO is thought to play a role in the regulation of the female reproductive function.
Catalytic Activity:
Histamine + H(2)O + O(2) = (imidazol-4-yl)acetaldehyde + NH(3) + H(2)O(2).
Cofactor:
COFACTOR: Name=Cu cation; Xref=ChEBI:CHEBI:23378;
Enzyme Regulation:
ENZYME REGULATION: Inhibited by isoniazid, cimetidine, clonidine, pentamidine, berenil and pentamidine.
Active Site:
ACT_SITE 373 373 Proton acceptor.
