THE STRUCTURE OF THE PEA LECTIN-D-MANNOPYRANOSE COMPLEX

The structure was published by Ruzheinikov, S.N., Mikhailova, I.Y., Tsygannik, I.N., Pangborn, W., Duax, W., and Pletnev, V.Z., in 1998 in a paper entitled "The Structure of the Pea Lectin-D-Mannopyranose Complex at a 2.1 A Resolution" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 1998.

The experimental data on which the structure is based was not deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely PROTEIN (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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
