ID   3.1.4.56
DE   7,8-dihydroneopterin 2',3'-cyclic phosphate phosphodiesterase.
CA   (1) 7,8-dihydroneopterin 2',3'-cyclic phosphate + H2O = 7,8-
CA   dihydroneopterin 3'-phosphate + H(+).
CA   (2) 7,8-dihydroneopterin 2',3'-cyclic phosphate + H2O = 7,8-
CA   dihydroneopterin 2'-phosphate + H(+).
CC   -!- Hydrolyzes 7,8-dihydroneopterin 2',3'-cyclic phosphate, a step in
CC       tetrahydromethanopterin biosynthesis.
CC   -!- In vitro the enzyme forms 7,8-dihydroneopterin 2'-phosphate and 7,8-
CC       dihydroneopterin 3'-phosphate at a ratio of 4:1.
