Reaction: (1) 5-phospho-α-D-ribose 1,2-cyclic phosphate + H2O = D-ribofuranose 2,5-bisphosphate
(2) D-ribofuranose 2,5-bisphosphate + H2O = D-ribofuranose 5-phosphate + phosphate
Other name(s): cyclic phosphate dihydrolase; phnPP (gene name)
Systematic name: 5-phospho-α-D-ribose 1,2-cyclic phosphate 1,2-diphosphophosphohydrolase
Comments: The enzyme, characterized from the bacterium Eggerthella lenta, is involed in degradation of methylphosphonate.
