The degradation of D-serine begins with the transport of D-serine into the cytosol through a cycA. Once in the cytosol D-serine reacts with ammonia-lyase resulting in the release of a hydrogen ion, water and a 2-aminoprop-2-enoate. This compound in turn reacts spontaneously to produces 2-iminipropanoate. This compound in turn reacts with water and hydrogen ion spontaneously resulting in the release of ammonium and apyruvate.
