1q8w Summary


The Catalytic Subunit of cAMP-dependent Protein Kinase in Complex with Rho-kinase Inhibitor Fasudil (HA-1077)

The structure was published by Breitenlechner, C., Gassel, M., Hidaka, H., et al., Huber, R., Engh, R.A., and Bossemeyer, D., in 2003 in a paper entitled "Protein kinase A in complex with Rho-kinase inhibitors Y-27632, Fasudil, and H-1152P: structural basis of selectivity." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 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.

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.
