Crystal structure of Dioclea rostrata lectin

The structure was published by de Oliveira, T.M., Delatorre, P., da Rocha, B.A.M., et al., Freire, V.N., de Azevedo Jr., W.F., and Cavada, B.S., in 2008 in a paper entitled "Crystal structure of Dioclea rostrata lectin: Insights into understanding the pH-dependent dimer-tetramer equilibrium and the structural basis for carbohydrate recognition in Diocleinae lectins" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.05 Å and deposited in 2007.

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

The PDB entry contains the structure of Lectin alpha chain. This molecule has the UniProt identifier P58908 (LECA_DIORO)search. The sample contained 237 residues which is 100% of the natural sequence. Out of 237 residues 231 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.
