2jpt Summary


Structural changes induced in apo-s100a1 protein by the disulphide formation between its CYS85 residue and b-mercaptoethanol

The structure was published by Zhukov, I., Ejchart, A., and Bierzynski, A., in 2008 in a paper entitled "Structural and motional changes induced in apo-S100A1 protein by the disulfide formation between its Cys 85 residue and beta-mercaptoethanol" (abstract).

The structure was determined using NMR spectroscopy and deposited in 2007.

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