2g4i Summary


Anomalous substructure of Concanavalin A

The structure was published by Mueller-Dieckmann, C., Panjikar, S., Schmidt, A., et al., Singh, R.K., Tucker, P.A., and Weiss, M.S., in 2007 in a paper entitled "On the routine use of soft X-rays in macromolecular crystallography. Part IV. Efficient determination of anomalous substructures in biomacromolecules using longer X-ray wavelengths." (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.
