SOLUTION STRUCTURE OF THE POTASSIUM CHANNEL INHIBITOR AGITOXIN 2: CALIPER FOR PROBING CHANNEL GEOMETRY

The structure was published by Krezel, A.M., Kasibhatla, C., Hidalgo, P., MacKinnon, R., and Wagner, G., in 1995 in a paper entitled "Solution structure of the potassium channel inhibitor agitoxin 2: caliper for probing channel geometry." (abstract).

The structure was determined using NMR spectroscopy and deposited in 1995.

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

The PDB entry contains the structure of AGITOXIN 2. This molecule has the UniProt identifier P46111 (KAX32_LEIQH)search. The sample contained 38 residues which is 100% of the natural sequence. Out of 38 residues 38 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
