PDB entry 2pel (supersedes 1pel)

PEANUT LECTIN

The structure was published by Banerjee, R., Das, K., Ravishankar, R., Suguna, K., Surolia, A., and Vijayan, M., in 1996 in a paper entitled "Conformation, protein-carbohydrate interactions and a novel subunit association in the refined structure of peanut lectin-lactose complex." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.25 Å and deposited in 1995.

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