Crystal structure of apoenzyme cAMP-dependent protein kinase catalytic subunit

The structure was published by Akamine, P., Madhusudan, Wu, J., Xuong, N.-H., Ten Eyck, L.F., and Taylor, S.S., in 2003 in a paper entitled "Dynamic Features of cAMP-dependent Protein Kinase Revealed by Apoenzyme Crystal Structure" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.9 Å and deposited in 2003.

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

This PDB entry contains multiple copies of the structure of cAMP-dependent protein kinase, alpha-catalytic subunit.

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.
