Peanut lectin complexed with 10mer peptide (PVRIWSSATG)

The structure was published by Kundhavai Natchiar, S., Arockia Jeyaprakash, A., Ramya, T.N., et al., Suguna, K., Surolia, A., and Vijayan, M., in 2004 in a paper entitled "Structural plasticity of peanut lectin: an X-ray analysis involving variation in pH, ligand binding and crystal structure." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.0 Å and deposited in 2003.

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