1nk3 Summary



The structure was published by Gruschus, J.M., Tsao, D.H., Wang, L.H., Nirenberg, M., and Ferretti, J.A., in 1997 in a paper entitled "Interactions of the vnd/NK-2 homeodomain with DNA by nuclear magnetic resonance spectroscopy: basis of binding specificity." (abstract).

The structure was determined using NMR spectroscopy and deposited in 1998.

The experimental data on which the structure is based was not deposited.
