ATP-dependent DNA helicase RecG, domain 3, C-terminal This domain is found in ATP-dependent DNA helicase RecG from bacteria the homologue from Arabidopsis, which has a critical role in recombination and DNA repair. This protein comprises three structural domains, the largest N-terminal Domain 1 which interacts with DNA junctions, and Domains 2 and 3 at the C-terminal which contain the characteristic motifs that identify RecG as an SF2 helicase. This domain represents the C-terminal of Domain 3. Around 50 residues that extend from its end cross back to Domain 1 forming a hook that wraps around the extended alpha-helix. This interaction provides a link between Domain 1 and 3 and it is likely that these residues are involved in conformational changes associated with domain movements arising from ATP binding and hydrolyzis. |
