Figure 2

Fructosamine oxidase (left, from 3dje.pdb) and E. coli DHOD (right, from 1f76.pdb) active site structures. The DHOD complex with orotate is shown, but the structure remains the same in its absence. Note that each enzyme has a lysine near N5 of the flavin. The structure of a Class 1A DHOD is not shown, but is essentially identical.
