Abstract

Crystals of a designed six-finger zinc-finger protein, Aart, bound to a 22-base-pair duplex DNA containing a consensus binding site have been obtained. Crystals grew by hanging-drop vapor diffusion from solutions containing polyethylene glycol 4000 as the precipitating agent. The irregularly shaped crystals belong to space group P1, with unit-cell parameters a = 41.95, b = 71.76, c = 74.73 Å, α = 100.87, β = 96.22, γ = 106.33°. There are most likely to be two protein-DNA complexes in the asymmetric unit. A complete native data set has been collected from a high-energy synchrotron source to a resolution of 2.95 Å at 100 K, with an R_merge of 9.3%.
