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

K+ ions moderately increases the Vmax, whereas UTP and Ca2+ and Mg2+ ions drastically increase the Km for GTP. 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.
