1sbd Summary



The structure was published by Olsen, L.R., Dessen, A., Gupta, D., Sabesan, S., Sacchettini, J.C., and Brewer, C.F., in 1997 in a paper entitled "X-ray crystallographic studies of unique cross-linked lattices between four isomeric biantennary oligosaccharides and soybean agglutinin." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.52 Å and deposited in 1995.

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

The PDB entry contains the structure of SOYBEAN AGGLUTININ. This molecule has the UniProt identifier P05046 (LEC_SOYBN)search. The sample contained 253 residues which is 100% of the natural sequence. Out of 253 residues 219 were observed and are deposited in the PDB.

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.
