2c3m Summary



The structure was published by Cavazza, C., Contreras-Martel, C., Pieulle, L., Chabriere, E., Hatchikian, E.C., and Fontecilla-Camps, J.C., in 2006 in a paper entitled "Flexibility of Thiamine Diphosphate Revealed by Kinetic Crystallographic Studies of the Reaction of Pyruvate-Ferredoxin Oxidoreductase with Pyruvate." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.84 Å and deposited in 2005.

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