Crystal structure analysis of CyaA/C-Cam with Pyrophosphate

The structure was published by Guo, Q., Shen, Y., Lee, Y.S., Gibbs, C.S., Mrksich, M., and Tang, W.J., in 2005 in a paper entitled "Structural basis for the interaction of Bordetella pertussis adenylyl cyclase toxin with calmodulin" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2005.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Bifunctional hemolysin-adenylate cyclase and Calmodulin.

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.
