1IEN sequence (synthetic) of Conus tulipa (fish-hunting cone snail)

REL
REL
This peptide was chemically syntesized. This sequence occurs in Conus marmoreus (mollusc-hunting cone snail). However, the C-terminus has been amidated whereas it exists as a free-acid in the native form.
sample
The sample was a purified single peptide component but on dissolution displayed evidence of
multiple conformations (manifest by peaks "brothering" in the N-terminal region). The structures
shown are for the major solution conformer.
The submitted conformer models are the 20 structures with the lowest energy.

The structures are calculated from a total of 82 distance restraints derived from 14 intra-residue,
42 sequential, 3 medium and 23 long range NOEs, and 4 dihedral restraints.
