1fnz Summary


A bark lectin from robinia pseudoacacia in complex with N-acetylgalactosamine

The structure was published by Rabijns, A., Verboven, C., Rouge, P., et al., Van Damme, E.J., Peumans, W.J., and De Ranter, C.J., in 2001 in a paper entitled "Structure of a legume lectin from the bark of Robinia pseudoacacia and its complex with N-acetylgalactosamine" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.05 Å and deposited in 2000.

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

The PDB entry contains the structure of BARK AGGLUTININ I, POLYPEPTIDE A. This molecule has the UniProt identifier Q41159 (LCB1_ROBPS)search. The sample contained 237 residues which is 93% of the natural sequence. Out of 237 residues 234 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.
