MutS is composed of several domains: N-terminal mismatch-recognition domain; connector domain; core domain; clamp domain; ATPase domain; helix-turn-helix domain. The complex between ''E. coli'' MutS and DNA in the scanning mode shows the straight DNA strand clamped between the two MutS monomers and held by the mismatch binding domain (residues 1-115) and the clamp domain (residues 444-503 <ref>PMID:33820992</ref>. In the 3D structure of the mismatch-bound MutS, the DNA strand is kinked by 60 degrees.
