Interpro abstract (IPR000489): | The ~250-residue pterin-binding domain has been shown to adopt a (beta/alpha)8 barrel fold, which has the overall shape of a distorted cylinder. It has eight alpha-helices stacked around the outside of an inner cylinder of parallel beta-strands. The pterin ring binds at the bottom of the (beta/alpha;)8 barrel in a polar cup-like region that is relatively solvent exposed and fairly negatively charged. The pterin ring is partially buried within the (beta/alpha)8 barrel. The pterin binding residues are highly conserved and include aspartate and asparagine residues located at the C terminus of the beta-strands of the barrel, which are predicted to form hydrogen bonds with the nitrogen and oxygen atoms of the pterin ring [ (PUBMED:10997901) (PUBMED:9187658) (PUBMED:14752199) ].
