Figure 1.

The FMN binding site of OYE1. Hydrogen bonds are shown as dashed lines and the distance between the atom attached to the donor hydrogen and the acceptor is shown in Å (Protein Data Bank ID code 1OYB). In this projection, the viewer is looking down on the si-face of the flavin. In this figure, H-atoms have been eliminated; N-atoms are displayed in blue, O-atoms in red, flavin C-atoms in orange, the P-atom in purple, and amino acid C-atoms in green.
