Atomic model for the N-terminus of TraO fitted in the full-length structure of the bacterial pKM101 type IV secretion system core complex

The structure was published by Rivera-Calzada, A., Fronzes, R., Savva, C.G., et al., Remaut, H., Waksman, G., and Orlova, E.V., in 2013 in a paper entitled "Structure of a Bacterial Type Iv Secretion Core Complex at Subnanometre Resolution." (abstract).

The structure was determined using Electron microscopy at a resolution of 12.4 Å and deposited in 2012.

The experimental data on which the structure is based was deposited separately in EMDB as entry 2232.

This PDB entry contains multiple copies of the structure of TRAO.

The most likely quaternary structure is a 14meric assembly.
