Function
FGE_THECD Oxidase that catalyzes the conversion of cysteine to 3-oxoalanine on target proteins. 3-oxoalanine modification, which is also named formylglycine (fGly), occurs in the maturation of arylsulfatases and some alkaline phosphatases that use the hydrated form of 3-oxoalanine as a catalytic nucleophile.[1] [2]
Publication Abstract from PubMed
The formylglycine-generating enzyme (FGE) is a unique copper protein that catalyzes oxygen-dependent C-H activation. We describe 1.66 A- and 1.28 A-resolution crystal structures of FGE from Thermomonospora curvata in complex with either AgI or CdII providing definitive evidence for a high-affinity metal-binding site in this enzyme. The structures reveal a bis-cysteine linear coordination of the monovalent metal, and tetrahedral coordination of the bivalent metal. Similar coordination changes may occur in the active enzyme as a result of CuI/II redox cycling. Complexation of copper atoms by two cysteine residues is common among copper-trafficking proteins, but is unprecedented for redox-active copper enzymes or synthetic copper catalysts.
