4a-hydroxytetrahydrobiopterin dehydratase

Template:Short description Template:Infobox enzyme The enzyme 4a-hydroxytetrahydrobiopterin dehydratase (Template:EnzExplorer) catalyzes the chemical reaction

4a-hydroxytetrahydrobiopterin $\rightleftharpoons$ 6,7-dihydrobiopterin + H₂O

This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is 4a-hydroxytetrahydrobiopterin hydro-lyase (6,7-dihydrobiopterin-forming). Other names in common use include 4a-hydroxy-tetrahydropterin dehydratase, pterin-4α-carbinolamine dehydratase, and 4a-hydroxytetrahydrobiopterin hydro-lyase.

Structural studies
