Crystal structure of small protein crambin at 0.48 A resolution

The structure was published by Schmidt, A., Teeter, M., Weckert, E., and Lamzin, V.S., in 2011 in a paper entitled "Crystal structure of small protein crambin at 0.48 A resolution" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 0.48 Å and deposited in 2010.

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

The PDB entry contains the structure of Crambin. This molecule has the UniProt identifier P01542 (CRAM_CRAAB)search. The sample contained 48 residues which is < 90% of the natural sequence. Out of 48 residues 48 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.
