3juh Summary


PDB entry 3juh (supersedes 3bw5)

Crystal structure of a mutant of human protein kinase CK2alpha with altered cosubstrate specificity

The structure was published by Yde, C.W., Ermakova, I., Issinger, O.-G., and Niefind, K., in 2005 in a paper entitled "Inclining the purine base binding plane in protein kinase CK2 by exchanging the flanking side-chains generates a preference for ATP as a cosubstrate" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.66 Å and deposited in 2009.

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

This PDB entry contains multiple copies of the structure of Casein kinase II subunit 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.
