Display the word mapDisplay the reaction diagram Show all sequences 2.7.7.B22cocrystal structures of the Hermes transposase bound to DNA that mimics the reaction step immediately prior to hairpin formation. A large DNA conformational change occurs between the initial cleavage step and subsequent hairpin formation that changes which strand is acted upon by a single active site. The complement of divalent metal ions bound by the catalytically essential DDE residues, and the identity of the -2 flanking base pair affect the conformationbal change. For efficient hairpin formation an A:T basepair is favored at the -2 position. The histidine residue within a conserved C/DxxH motif interacts directly with the scissile phosphate 762045
Display the word mapDisplay the reaction diagram Show all sequences 2.7.7.B22cryo-EM structures of piggyBac transpososomes show a synaptic complex with hairpin DNA intermediates and a strand transfer complex capturing the integration step. The excised TTAA hairpin intermediate and the TTAA target adopt essentially identical conformations. The transposase forms an asymmetric dimer in which the two central domains synapse the ends while two C-terminal domains form a separate dimer that contacts only one transposon end. In the strand transfer structure, target DNA is severely bent and the TTAA target is unpaired 761979
