Crystal Structure Analysis of crosslinked-WGA3/GlcNAcbeta1,4GlcNAc complex

The structure was published by Muraki, M., Ishimura, M., and Harata, K., in 2002 in a paper entitled "Interactions of wheat-germ agglutinin with GlcNAc beta 1,6Gal sequence" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2001.

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

This PDB entry contains multiple copies of the structure of agglutinin isolectin 3.

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