Crystal structure of Anthrax Lethal Factor wild-type protein complexed with an optimised peptide substrate.

The structure was published by Turk, B.E., Wong, T.Y., Schwarzenbacher, R., et al., Collier, R.J., Liddington, R.C., and Cantley, L.C., in 2004 in a paper entitled "The structural basis for substrate and inhibitor selectivity of the anthrax lethal factor." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.85 Å and deposited in 2003.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Lethal factor and LF20.

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