STRUCTURE OF PKA-PKB CHIMERA COMPLEXED WITH (R)-2-(4-CHLORO-PHENYL)-2-(4-1H-PYRAZOL-4-YL)-PHENYL)-ETHYLAMINE

The structure was published by Saxty, G., Woodhead, S.J., Berdini, V., et al., Downham, R., Garrett, M.D., and Carr, R.A., in 2007 in a paper entitled "Identification of Inhibitors of Protein Kinase B Using Fragment-Based Lead Discovery" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.14 Å and deposited in 2007.

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

This PDB entry contains a complex of 2 biomacromolecules, namely CAMP-DEPENDENT PROTEIN KINASE, ALPHA-CATALYTIC SUBUNIT and CAMP-DEPENDENT PROTEIN KINASE INHIBITOR ALPHA.

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 most likely forms heterodimers.
