3lk0 Summary


X-ray structure of bovine SC0067,Ca(2+)-S100B

The structure was published by Wilder, P.T., Charpentier, T.H., Liriano, M.A., et al., Toth, E.A., Mackerell, A.D., and Weber, D.J., in 2010 in a paper entitled "In vitro screening and structural characterization of inhibitors of the S100B-p53 interaction." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.04 Å and deposited in 2010.

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