title: Peptide toxins from Conus geographus venom.
abstract: Three homologous toxic peptides which cause postsynaptic inhibition at the vertebrate neuromuscular junction have been purified from the venom of the marine snail Conus geographus. Their amino acid sequences are: (formula see text) The biologically active peptides are monomeric, with internal disulfide bonds.
