PKA double mutant model of PKB

The structure was published by Gassel, M., Breitenlechner, C.B., Rueger, P., et al., Huber, R., Bossemeyer, D., and Engh, R.A., in 2003 in a paper entitled "Mutants of protein kinase A that mimic the ATP-binding site of protein kinase B (AKT)" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 2003.

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 form.

The molecule most likely forms heterodimers.
