Reaction: ADP-ribose 1"-phosphate + H2O = ADP-D-ribose + phosphate
Other name(s): POA1; Appr1p phosphatase; Poa1p; ADP-ribose 1"-phosphate phosphohydrolase
Systematic name: ADP-D-ribose 1"-phosphate phosphohydrolase
Comments: The enzyme is highly specific for ADP-ribose 1"-phosphate. Involved together with EC 184.108.40.206, 2',3'-cyclic-nucleotide 3'-phosphodiesterase, in the breakdown of adenosine diphosphate ribose 1",2"-cyclic phosphate (Appr>p), a by-product of tRNA splicing.
