XEASY Sequence List

Sequence List

The XEASY sequence list defines the primary sequence of the biomolecule. In the initial phases of an assignment cycle, it is advantageous to use generic spin-system names such as SS for conventional spectra or SRD for reduced dimensionality spectra and GFT spectra. The sequence file will contain only the residue type and the residue number (shown below).

when columns 1 to 3 are residue name, fragment number and mapping number, respectively. The mapping number defines a residue's real position in the protein sequence.
