Figure 4.
Fig. 4. Direct and water-mediated interactions between MutM and
the DNA backbone in the control LRC CC2 (A) and interrogation
complexes IC1 (B) and IC2 (C). Dashed lines indicate hydrogen
bonding interactions among backbone phosphates in DNA, ordered
waters (red spheres), and residues in MutM. The side chains of
amino acid residues are shown in green with the numbers colored
according to which moiety on the amino acid is involved in the
contact: green, side chain; blue, backbone amide NH; red,
backbone amide carbonyl; gray, no contact in that particular
complex.
