2gww Summary


Human vinculin (head domain, Vh1, residues 1-258) in complex with Shigella's IpaA vinculin binding site (residues 602-633)

The structure was published by Izard, T., Tran Van Nhieu, G., and Bois, P.R., in 2006 in a paper entitled "Shigella applies molecular mimicry to subvert vinculin and invade host cells." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.72 Å and deposited in 2006.

The experimental data on which the structure is based was not deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely vinculin and IpaA.
