3tj6 Summary

pdbe.org/3tj6
spacer

human vinculin head domain (Vh1, residues 1-258) in complex with the vinculin binding site of the surface cell antigen 4 (sca4-VBS-C; residues 812-835) from Rickettsia rickettsii

The structure was published by Park, H., Lee, J.H., Gouin, E., Cossart, P., and Izard, T., in 2011 in a paper entitled "The rickettsia surface cell antigen 4 applies mimicry to bind to and activate vinculin." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.76 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 Antigenic heat-stable 120 kDa protein.

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