Description
The reaction involves hydrolysis of two C-N bonds and isomerization of the pentose unit; the recyclization may be non-enzymic. This enzyme is involved in the de novo synthesis of tetrahydrobiopterin from GTP, with the other enzymes involved being EC 1.1.1.153 (sepiapterin reductase) and EC 4.2.3.12 (6-pyruvoyltetrahydropterin synthase).
Form
Liquid or lyophilized powder
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC~-80 ºC.
Synonyms
GTP cyclohydrolase; guanosine triphosphate cyclohydrolase; guanosine triphosphate 8-deformylase; dihydroneopterin triphosphate synthase; GTP 8-formylhydrolase
Reaction
GTP + H2O = formate + 7,8-dihydroneopterin 3'-triphosphate
