General annotation (Comments)

Function

The enzyme prefers aromatic over aliphatic amines.

Catalytic activity

RCH2NH2 + H2O + O2 = RCHO + NH3 + H2O2.

2-phenylethylamine + H2O + O2 = phenylacetaldehyde + NH3 + H2O2.

Cofactor

Binds 1 copper ion per subunit.

Binds 2 calcium ions per subunit.

Contains 1 topaquinone per subunit.

Pathway

Amino-acid degradation; L-phenylalanine degradation; phenylacetate from L-phenylalanine: step 2/3.

Subunit structure

Homodimer.

Subcellular location

Periplasm.

Post-translational modification

Topaquinone (TPQ) is generated by copper-dependent autoxidation of a specific tyrosyl residue.

Sequence similarities

Belongs to the copper/topaquinone oxidase family.

Caution

When highly overexpressed there can be substoichiometric amounts of TPQ in the enzyme; this may be due to imperfect conversion of tyrosine to TPQ (see Ref.3).
