1gkb Summary


PDB entry 1gkb (supersedes 1e0i)


The structure was published by Kantardjieff, K., Hochtl, P., Segelke, B., Tao, F., and Rupp, B., in 2002 in a paper entitled "Concanavalin a in a Dimeric Crystal Form: Revisiting Structural Accuracy and Molecular Flexibility" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.56 Å and deposited in 2001.

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