Metal-free (apo) P. angolensis seed lectin in complex with GlcNAC-beta(1-2)Man

The structure was published by Garcia-Pino, A., Buts, L., Wyns, L., and Loris, R., in 2006 in a paper entitled "Interplay Between Metal Binding and cis/trans Isomerization in Legume Lectins: Structural and Thermodynamic Study of P. angolensis Lectin." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 2006.

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

This PDB entry contains multiple copies of the structure of lectin.

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 homodimers.
