DETERMINATION OF THE THREE-DIMENSIONAL STRUCTURE OF MARGATOXIN BY 1H, 13C, 15N TRIPLE-RESONANCE NUCLEAR MAGNETIC RESONANCE SPECTROSCOPY

The structure was published by Johnson, B.A., Stevens, S.P., and Williamson, J.M., in 1994 in a paper entitled "Determination of the three-dimensional structure of margatoxin by 1H, 13C, 15N triple-resonance nuclear magnetic resonance spectroscopy." (abstract).

The structure was determined using NMR spectroscopy and deposited in 1994.

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

The PDB entry contains the structure of MARGATOXIN. This molecule has the UniProt identifier P40755 (KAX22_CENMA)search. The sample contained 39 residues which is 100% of the natural sequence. Out of 39 residues 39 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
