General annotation (Comments)

Catalytic activity

GTP + H2O = formate + 2-amino-4-hydroxy-6-(erythro-1,2,3-trihydroxypropyl)-dihydropteridine triphosphate. HAMAP-Rule MF_00223

Enzyme regulation

Allosteric enzyme. Activity is modulated by K+, divalent cations, UTP, and tetrahydrobiopterin. Tetrahydrobiopterin is an inhibitor of this enzyme By similarity. HAMAP-Rule MF_00223

Pathway

Cofactor biosynthesis; 7,8-dihydroneopterin triphosphate biosynthesis; 7,8-dihydroneopterin triphosphate from GTP: step 1/1. HAMAP-Rule MF_00223

Subunit structure

Toroid-shaped homodecamer, composed of two pentamers of five dimers By similarity.

Sequence similarities

Belongs to the GTP cyclohydrolase I family.
