CC   -!- CATALYTIC ACTIVITY: GTP + H(2)O = formate + 2-amino-4-hydroxy-6-
CC       (erythro-1,2,3-trihydroxypropyl)-dihydropteridine triphosphate.
CC   -!- PATHWAY: Cofactor biosynthesis; dihydroneopterin triphosphate
CC       biosynthesis; 2-amino-4-hydroxy-6-(erythro-1,2,3-
CC       trihydroxypropyl)-dihydropteridine triphosphate from GTP: step
CC       1/1.
CC   -!- SUBUNIT: Toroid-shaped homodecamer, composed of two pentamers of
CC       five dimers (By similarity).
CC   -!- SIMILARITY: Belongs to the GTP cyclohydrolase I family.
