in the first step of the reaction, which is the only enzymatic step of the whole reaction scheme, DDO catalyzes the dehydrogenation of a D-amino acid to generate the corresponding imino acid, coupled with the reduction of FAD. Subsequently, FAD reoxidizes spontaneously in the presence of O2, producing H2O2, while the imino acid nonenzymatically hydrolyzes to 2-oxo acid and NH3

DASPO plays an essential role in the assimilation of D-aspartate and acts as a detoxifying agent for D-aspartate. In the wild-type strain, the induction of ChDASPO activity strictly depends on the presence of D-aspartate and is little affected by the copresence of ammonium chloride, but it is significantly reduced by the copresence of both glucose and ammonium chloride, which, however, did not abolish the induction, allowing considerable expression of ChDASPO

DASPO plays an essential role in the assimilation of D-aspartate and acts as a detoxifying agent for D-aspartate. In the wild-type strain, the induction of ChDASPO activity strictly depends on the presence of D-aspartate and is little affected by the copresence of ammonium chloride, but it is significantly reduced by the copresence of both glucose and ammonium chloride, which, however, did not abolish the induction, allowing considerable expression of ChDASPO
