X-RAY STRUCTURE OF A (ALPHA-MAN(1-3)BETA-MAN(1-4)GLCNAC)-LECTIN COMPLEX AT 2.1 ANGSTROMS RESOLUTION

The structure was published by Bourne, Y., Rouge, P., and Cambillau, C., in 1990 in a paper entitled "X-ray structure of a (alpha-Man(1-3)beta-Man(1-4)GlcNAc)-lectin complex at 2.1-A resolution. The role of water in sugar-lectin interaction." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 1994.

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

This PDB entry contains a complex of 2 biomacromolecules, namely LEGUME ISOLECTIN I (ALPHA CHAIN) and LEGUME ISOLECTIN I (BETA CHAIN).

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.
