2gni Summary


PKA fivefold mutant model of Rho-kinase with inhibitor Fasudil (HA1077)

The structure was published by Bonn, S., Herrero, S., Breitenlechner, C.B., et al., Engh, R.A., Gassel, M., and Bossemeyer, D., in 2006 in a paper entitled "Structural analysis of protein kinase A mutants with Rho-kinase inhibitor specificity" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.27 Å and deposited in 2006.

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.
