Comments
Although the first domain of this enzyme is classified in CATH 3.40.50.720, it should be homologous to sarcosine oxidase (E.C. 1.5.3.1; D00041 in EzCatDB), and is re-classified into CATH 3.50.50.60 in this database.
Although this enzyme is homologous to yeast counterpart (D00494 in EzCatDB), a set of catalytic residues is slightly different from the counterpart. The sidechain of Tyr224 plays a catalytic role as the counterpart of corresponding Ser335 in the yeast enzyme (see D00494) (see [15] & [26]).
According to the literature [22], this enzyme catalyzes the following reactions:
(A) Hydride transfer from D-amino acid to FAD, giving imino acid and FADH2 (reductive half-reaction).
(B) Hydride transfer from FADH2 to O2, giving FAD and H2O2 (oxidative half-reaction).
(C) Exchange of double-bonded atoms of the imino acid (Schiff-base deformation by water)
