McrB AAA+(H2-insert clade) Heptamer dsDNA Type IV restriction enzymes Bacterial McrB figure legend: topology diagrams of Helicases and translocases The RecA and AAA+ folds are built from an ancestral αβα ASCE domain (turquoise). The relative position of bound nucleotide is shown, and certain nucleoside-triphosphate binding motifs are highlighted (sensor I; sensor II; arginine-finger; Walker-A and Walker-B motifs). The catalytic glutamic acid of the Walker-B motif can occupy alternative positions in some subfamilies (pale red spheres). The AAA+ sensor-I amino acid is generally a polar residue that is also found in other ASCE proteins. Triangles represent common insertion points for domains or secondary structural elements that are specific to select helicase and translocase groups (eg, domains IB and IIB of SF-I helicases, or the pre-sensor I β hairpin of AAA+ proteins). The diverse placement of arginine finger elements arises from distinct tertiary and quaternary arrangements of domains or subunits in different subfamilies.
