STRUCTURE OF HUMAN THR160-PHOSPHO CDK2/CYCLIN A COMPLEXED WITH THE INHIBITOR NU6102

The structure was published by Davies, T.G., Bentley, J., Arris, C.E., et al., Tucker, J.A., Wang, L., and Whitfield, H.J., in 2002 in a paper entitled "Structure-Based Design of a Potent Purine-Based Cyclin-Dependent Kinase Inhibitor" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2002.

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

This PDB entry contains a complex of 2 biomacromolecules, namely CELL DIVISION PROTEIN KINASE 2 and CYCLIN A2.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule has more than one probable quaternary state observed. For more details see the quaternary structure page.
