IUBMB Enzyme Nomenclature

EC 3.1.3.84

Accepted name: ADP-ribose 1"-phosphate phosphatase

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 3.1.4.37, 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.
