3rf3 Summary


Shigella IpaA-VBS3 in complex with human vinculin

The structure was published by Park, H., Valencia-Gallardo, C., Sharff, A., Tran Van Nhieu, G., and Izard, T., in 2011 in a paper entitled "Novel vinculin binding site of the IpaA invasin of Shigella." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.61 Å and deposited in 2011.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Vinculin and Invasin ipaA.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
