When DNA is bent around a protein, it must distort. The distortion occurs by changes in the conformation of successive dinucleotide steps. Bending does not necessarily occur uniformly: some steps might remain particularly rigid, i.e. they might deform relatively little, while others might take more than their proportional share of deformation. We investigate here the deformational capacity of specific dinucleotide steps by examining a database of crystallized oligomers. Dividing the steps into… CONTINUE READING
