Protein existence	Inferred from homology

General annotation (Comments)

Catalytic activity	GTP + H2O = formate + 2-amino-4-hydroxy-6-(erythro-1,2,3-trihydroxypropyl)-dihydropteridine triphosphate. 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.
Sequence caution	The sequence AAO90329.2 differs from that shown. Reason: Erroneous initiation.
