2iw9 Summary



The structure was published by Pratt, D.J., Bentley, J., Jewsbury, P., Boyle, F.T., Endicott, J.A., and Noble, M.E.M., in 2006 in a paper entitled "Dissecting the Determinants of Cyclin-Dependent Kinase 2 and Cyclin-Dependent Kinase 4 Inhibitor Selectivity." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2006.

The experimental data on which the structure is based was also deposited.
