Crystal Structure of meso-tetrasulphonatophenyl porphyrin complexed with Concanavalin A

The structure was published by Goel, M., Jain, D., Kaur, K.J., et al., Maiya, B.G., Swamy, M.J., and Salunke, D.M., in 2000 in a paper entitled "Functional equality in the absence of structural similarity: an added dimension to molecular mimicry" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2001.

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

The PDB entry contains the structure of Concanavalin A. This molecule has the UniProt identifier P02866 (CONA_CANEN)search. The sample contained 237 residues which is < 90% of the natural sequence. Out of 237 residues 237 were observed and are deposited in the PDB.

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.
