FIGURE 4. FitA-DNA contacts. a, schematic diagram of the
FitA-DNA contacts. The deoxyriboses of each nucleotide are
numbered, labeled, and shown as pentagons. Side chain DNA
hydrogen bonds are indicated by blue arrows, backbone amide-DNA
hydrogen bonds are green arrows, and van der Waals contacts are
shown as yellow arrows. Each FitA residue is from subunit I, II,
III, or IV, as defined in the legend to Fig. 2. b, stereo view
of the composite omit electron density map of one FitA-DNA
interface contoured at 1.0 to 3.0 Å
resolution (green mesh). The FitA protein is shown as magenta
balls and sticks and the DNA is shown as balls and sticks where
gray (carbon), red (oxygen), blue (nitrogen), yellow
(phosphorus). Note the water (Wat1)-mediated contact between
Asn^8 and Thy^32'.
