SOLUTION STRUCTURE OF CA(2+)-LOADED RAT S100B (BETABETA) NMR, 20 STRUCTURES

The structure was published by Drohat, A.C., Baldisseri, D.M., Rustandi, R.R., and Weber, D.J., in 1998 in a paper entitled "Solution structure of calcium-bound rat S100B(betabeta) as determined by nuclear magnetic resonance spectroscopy,." (abstract).

The structure was determined using NMR spectroscopy and deposited in 1997.

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