Crystal structure of the flagellar type III ATPase FliI

The structure was published by Imada, K., Minamino, T., Tahara, A., and Namba, K., in 2007 in a paper entitled "Structural similarity between the flagellar type III ATPase FliI and F1-ATPase subunits" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 2006.

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

This PDB entry contains multiple copies of the structure of Flagellum-specific ATP synthase.

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.
