CC -!- FUNCTION: GTP cyclohydrolase 1 is the first enzyme in the biosynthetic
CC pathway leading to folic acid.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GTP + H2O = 7,8-dihydroneopterin 3'-triphosphate + formate +
CC H(+); Xref=Rhea:RHEA:17473, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:15740, ChEBI:CHEBI:37565, ChEBI:CHEBI:58462; EC=3.5.4.16;
CC -!- ACTIVITY REGULATION: GTP shows a positive allosteric effect, and
CC tetrahydrobiopterin inhibits the enzyme activity. {ECO:0000250}.
CC -!- PATHWAY: Cofactor biosynthesis; 7,8-dihydroneopterin triphosphate
CC biosynthesis; 7,8-dihydroneopterin triphosphate from GTP: step 1/1.
CC -!- SUBUNIT: Toroid-shaped homodecamer, composed of two pentamers of five
CC dimers. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the GTP cyclohydrolase I family. {ECO:0000305}.
