FUNCTION | Catalyzes the formation of 2-amino-5-formylamino-6- ribofuranosylamino-4(3H)-pyrimidinone ribonucleotide monophosphate and inorganic phosphate from GTP. Also has an independent pyrophosphate phosphohydrolase activity. |
CATALYTIC ACTIVITY | Reaction=GTP + 3 H2O = 2-amino-5-formylamino-6-(5-phospho-D- ribosylamino)pyrimidin-4(3H)-one + 2 H(+) + 2 phosphate; Xref=Rhea:RHEA:22468, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:37565, ChEBI:CHEBI:43474, ChEBI:CHEBI:57258; EC=3.5.4.29; |
SIMILARITY | Belongs to the archaeal-type GTP cyclohydrolase family. |
