Figure 3. (a) The network of hydrogen bonds between the
cofactor FMN and protein. The enzyme is drawn by a ball and
stick model. Hydrogen atoms are omitted from this Figure for
clarity. Each atom is colored according to atom type (carbon of
protein in silver, carbon of FMN in yellow). Protein residues
and N5 and N1 atoms of FMN are labeled. Hydrogen bonds are
indicated with red broken lines. (b) Electron density of FMN and
surrounding residues from a 2 F[o]−F[c]map contoured at one
σ. The FMN and its phosphate atom as well as some surrounding
residues are labeled. In this and all subsequent Figures, the
one letter code for amino acid names is used for enhanced
clarity.
