GTP cyclohydrolase 1

Gene

folE

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Catalytic activityi

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

Enzyme regulationi

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