3cr2 Summary


X-ray structure of bovine Zn(2+),Ca(2+)-S100B

The structure was published by Charpentier, T.H., Wilder, P.T., Liriano, M.A., et al., Coop, A., Toth, E.A., and Weber, D.J., in 2008 in a paper entitled "Divalent metal ion complexes of S100B in the absence and presence of pentamidine." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.88 Å and deposited in 2008.

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

The PDB entry contains the structure of Protein S100-B. This molecule has the UniProt identifier P02638 (S100B_BOVIN)search. The sample contained 92 residues which is 100% of the natural sequence. Out of 92 residues 88 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 homodimers.
