CC -!- FUNCTION: May positively regulate nitric oxide synthesis in endothelial
CC cells. May be involved in dopamine synthesis. May modify pain
CC sensitivity and persistence. {ECO:0000250|UniProtKB:P30793}.
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 Evidence={ECO:0000250|UniProtKB:P30793};
CC -!- ACTIVITY REGULATION: GTP shows a positive allosteric effect, and
CC tetrahydrobiopterin inhibits the enzyme activity. Zinc is required for
CC catalytic activity. Inhibited by Mg(2+).
CC {ECO:0000250|UniProtKB:P30793}.
CC -!- PATHWAY: Cofactor biosynthesis; 7,8-dihydroneopterin triphosphate
CC biosynthesis; 7,8-dihydroneopterin triphosphate from GTP: step 1/1.
CC {ECO:0000250|UniProtKB:P30793}.
CC -!- SUBUNIT: Toroid-shaped homodecamer, composed of two pentamers of five
CC dimers. Interacts with AHSA1 and GCHFR/GFRP.
CC {ECO:0000250|UniProtKB:P30793}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P30793}. Nucleus
CC {ECO:0000250|UniProtKB:P30793}.
CC -!- PTM: Phosphorylated. {ECO:0000250|UniProtKB:P30793}.
CC -!- SIMILARITY: Belongs to the GTP cyclohydrolase I family. {ECO:0000305}.
