2k7o Summary


Ca2+-S100B, refined with RDCs

The structure was published by Wright, N.T., Inman, K.G., Levine, J.A., Cannon, B.R., Varney, K.M., and Weber, D.J., in 2008 in a paper entitled "Refinement of the solution structure and dynamic properties of Ca(2+)-bound rat S100B." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2008.

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