Mu B transposition protein, C terminal The C terminal domain of the B transposition protein from Bacteriophage Mu comprises four alpha-helices arranged in a loosely packed bundle, where helix alpha1 runs parallel to alpha3, and anti-parallel to helices alpha2 and alpha4. The domain allows for non-specific binding of Mu to double-stranded DNA, allowing for integration into the bacterial genome, and mediates dimerization of the protein.
