CONCANAVALIN A/15-mer PEPTIDE COMPLEX

The structure was published by Jain, D., Kaur, K.J., and Salunke, D.M., in 2001 in a paper entitled "Plasticity in Protein-Peptide Recognition: Crystal Structures of Two Different Peptides Bound to Concanavalin A" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.75 Å and deposited in 2001.

The experimental data on which the structure is based was not deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely Concanavalin A and 15-mer peptide.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule has more than one probable quaternary state observed. For more details see the quaternary structure page.
