Comments
The catalytic domain of this enzyme is homologous to those of counterpart enzymes from E. coli (M00103 in EzCatDB), from pea (T00250 in EzCatDB), from bovine (T00251 in EzCatDB), and membrane-protein from human (M00202 in EzCatDB).
Cofactor, topaquinone (2,4,5-trihydroxyphenylalanine), is a modified residue, generated from active site tyrosine residue (Tyr471) by self-catalysis (see [6] of M00103 in EzCatDB). Some literature described biogenesis of this residue, along with the catalytic mechanism.
According to the literature [24], and [9] (for its homologue), this enzyme catalyzes two half-reactions: (I) reductive half-reaction, and (II) oxidative half-reaction. These half-reactions can be subdivided into several basic reactions in terms of RLCP classification.
(I) Reductive half-reaction:
(A) Exchange of double-bonded atoms; Schiff-base formation; Substrate amine forms a Schiff-base with topaquinone, generating iminoquinone=substrate and H2O (dehydration):
(B) Isomerization from iminoquinone=substrate complex to aminoquinol=product complex (through a carbanionic intermediate):
(C) Exchange of double-bonded atoms; Schiff-base deformation; H2O reacts with the intermediate, generating aminoquinol and product aldehyde (hydration):
(II) Oxidative half-reaction:
(D) Reduction of dioxygen (O2) by aminoquinol, to produce hydrogen peroxide (H2O2) and iminoquinone (Hydride transfer):
(E) Exchange of double-bonded atoms; Schiff-base deformation; H2O reacts with the intermediate, generating topaquinone and product ammonia (hydration):
