Solution structure of a bacterial cyclic nucleotide-activated K+ channel binding domain in the unliganded state

The structure was published by Schunke, S., Stoldt, M., Lecher, J., Kaupp, U.B., and Willbold, D., in 2011 in a paper entitled "Structural insights into conformational changes of a cyclic nucleotide-binding domain in solution from Mesorhizobium loti K1 channel." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2010.

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

The PDB entry contains the structure of Cyclic nucleotide-gated potassium channel mll3241. This molecule has the UniProt identifier Q98GN8 (CNGK1_RHILO)search. The sample contained 142 residues which is < 90% of the natural sequence. Out of 142 residues 142 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
