Crystal structure of peanut lectin lactose-azobenzene-4,4'-dicarboxylic acid-lactose complex

The structure was published by Natchiar, S.K., Srinivas, O., Nivedita, M., et al., Jayaraman, N., Surolia, A., and Vijayan, M., in 2006 in a paper entitled "Multivalency in lectins - A crystallographic, modelling and light-scattering study involving peanut lectin and a bivalent ligand" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 7.65 Å and deposited in 2006.

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

This PDB entry contains multiple copies of the structure of Galactose-binding lectin.
