Comparison of the crystal structure of a complex of the phage 434 Cro protein and a synthetic DNA operator with the complex of the same operator and the 434 repressor DNA-binding domain shows different DNA conformations in the two structures. Binding of the protein determines the precise conformation of the DNA in each case.
噬菌体434 Cro蛋白与合成DNA操纵基因复合物的晶体结构，同相同操纵基因与434阻遏蛋白DNA结合结构域复合物的晶体结构相比，显示出两种结构中DNA构象不同。在每种情况下，蛋白质的结合决定了DNA的精确构象。
