The crystal structure of the calcium binding protein AtCBL2 from Arabidopsis thaliana

The structure was published by Nagae, M., Nozawa, A., Koizumi, N., et al., Hashimoto, H., Sato, M., and Shimizu, T., in 2003 in a paper entitled "The Crystal Structure of the Novel Calcium-binding Protein AtCBL2 from Arabidopsis thaliana" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2003.

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

The PDB entry contains the structure of calcineurin B-like protein 2. This molecule has the UniProt identifier Q8LAS7 (CNBL2_ARATH)search. The sample contained 189 residues which is < 90% of the natural sequence. Out of 189 residues 188 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.
