X-RAY STRUCTURE OF A BIANTENNARY OCTASACCHARIDE-LECTIN COMPLEX AT 2.3 ANGSTROMS RESOLUTION

The structure was published by Bourne, Y., Rouge, P., and Cambillau, C., in 1992 in a paper entitled "X-ray structure of a biantennary octasaccharide-lectin complex refined at 2.3-A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 1993.

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

This entry contains 15 copies of 4 unique biopolymers (complete list).

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.
