Exploring the Structure

You can take a closer look at glucose oxidase from a Penicillium mold in PDB entry 1gpe. The oxidation reaction is performed by the FAD cofactors bound deep inside the enzyme, shown in red. The active site where glucose binds is just above the FAD, in a deep pocket shown with a star. Notice that the enzyme, like many proteins that act outside of cells, is covered with carbohydrate chains, shown in green.
