Other Details The 3D reconstruction is not representative of the complex in solution. The Hermes transposase forms a tetramer of dimers assembled in a ring like shape. Due to their low resolution two Hermes dimers have been partially or completely masked out during the processing. Only the opposite two Hermes dimers interacting with the DNAs have been fully reconstructed, along with the two DNAs and the two BED domains of a third Hermes dimer.
