1b4c Summary



The structure was published by Drohat, A.C., Tjandra, N., Baldisseri, D.M., and Weber, D.J., in 1999 in a paper entitled "The use of dipolar couplings for determining the solution structure of rat apo-S100B(betabeta)." (abstract).

The structure was determined using NMR spectroscopy and deposited in 1998.

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