LECTIN II FROM ULEX EUROPAEUS

The structure was published by Loris, R., De Greve, H., Dao-Thi, M.-H., Messens, J., Imberty, A., and Wyns, L., in 2000 in a paper entitled "Structural Basis of Carbohydrate Recognition by Lectin II from Ulex Europaeus, a Protein with a Promiscuous Carbohydrate Binding Site" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.35 Å and deposited in 1999.

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

This PDB entry contains multiple copies of the structure of CHITIN BINDING LECTIN, UEA-II.

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 most likely forms homotetramers.
