(a) A space-filling model of B-DNA showing the relative accessibility of the major and minor grooves. (b) A helix of the 434 repressor bound in the major groove of the helix, illustrating how the dimensions of a protein α-helix are compatible for reading the major groove of B-DNA (Shimon & Harrison, 1993).
