3n35 Summary


Erythrina corallodendron lectin mutant (Y106G) with N-Acetylgalactosamine

The structure was published by Thamotharan, S., Karthikeyan, T., Kulkarni, K.A., et al., Surolia, A., Vijayan, M., and Suguna, K., in 2011 in a paper entitled "Modification of the sugar specificity of a plant lectin: structural studies on a point mutant of Erythrina corallodendron lectin." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2010.

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

The PDB entry contains the structure of Lectin. This molecule has the UniProt identifier P16404 (LEC_ERYCO)search. The sample contained 242 residues which is 95% of the natural sequence. Out of 242 residues 242 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 is most likely monomeric.
