THE 2.0 A STRUCTURE OF HOLO S100B FROM BOVINE BRAIN

The structure was published by Matsumura, H., Shiba, T., Inoue, T., Harada, S., and Kai, Y., in 1998 in a paper entitled "A novel mode of target recognition suggested by the 2.0 A structure of holo S100B from bovine brain." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1997.

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

The PDB entry contains the structure of S-100 PROTEIN. This molecule has the UniProt identifier P02638 (S100B_BOVIN)search. The sample contained 88 residues which is 96% of the natural sequence. Out of 88 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.
