Figure 4. BstUvrA Dimer Interface C[α] trace of
protomers A and B are shown in pale green and pale blue,
respectively, with the Zn atoms in gray. The regions involved in
polar contacts across the dimer interface are shown using ribbon
diagram (green and orange, protomer A; blue and magenta,
protomer B). Hydrogen bonds are depicted as dashed lines and the
bound ADP molecules as space-filling models. Illustrations in
(A) –(C) are shown in the same orientation as in Figure 1B.
(A) UvrA dimer. (B) Interactions between the Q loop-I
and the loop following α helix 1, which contains the Walker A-I
motif at its N terminus. (C) Interactions between the loop
preceding Walker B-I and residues of the ATP-binding domain I of
the opposing monomer.
