Function
Removes ADP-ribose from asparatate and glutamate residues in proteins bearing a single ADP-ribose moiety (PubMed:23474714, PubMed:23474712). Inactive towards proteins bearing poly-ADP-ribose (PubMed:23474714, PubMed:23474712). Catalyzes removal of a phosphate group from ADP-ribose 1''-phosphate (Appr1p), but with low efficiency (PubMed:15902274).
