NMR Structure of the Response regulator CheY2 from Sinorhizobium meliloti, complexed with Mg++

The structure was published by Riepl, H., Scharf, B., Schmitt, R., Kalbitzer, H.R., and Maurer, T., in 2004 in a paper entitled "Solution structures of the inactive and BeF3-activated response regulator CheY2." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2003.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of CheY2. This molecule has the UniProt identifier Q52884 (Q52884_RHIML)search. The sample contained 129 residues which is 100% of the natural sequence. Out of 129 residues 129 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
