Pterin-4 alpha-carbinolamine dehydratase deficiency
Pterin-4 alpha-carbinolamine dehydratase deficiency (PCDD) is one of the known forms of tetrahydrobiopterin deficiency. Diagnosis Pterin-4 alpha-carbinolamine dehydratase deficiency causes hyperphenylalaninemia and therefore can be suspected upon finding elevated levels wikipedia.org

Aldehyde ferredoxin oxidoreductase
Thus, pterin and Tungsten atoms are connected to the AOR enzyme primarily through pterin's Hydrogen bonding networks with the amino acid residues. Also, another linker amino acid residue between ferredoxin cluster and pterin is the Arg76, which hydrogen bonds to both pterin and ferredoxin. wikipedia.org
