4a-hydroxytetrahydrobiopterin dehydratase
Template:Short description Template:Infobox enzyme The enzyme 4a-hydroxytetrahydrobiopterin dehydratase (Template:EnzExplorer) catalyzes the chemical reaction
- 4a-hydroxytetrahydrobiopterin 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
As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes 1DCO, 1DCP, and 1RU0.
