The following codes should be used for the unusual
peptides :
Note : Some records contain entries where
residues were not fully identified. In these cases, the
sequences contain residues marked with an x to signify this
fact. The three letter codes correspondingly use 'xx'. Where leucine could not be distinguished from isoleucine,
records are marked Lx or Lxx. Examples : Reminder of common amino acid codes. Search for peptaibol by source mould :Enter the name (or part of the name) of the source mould to search for.Examples: Searching for "ampull" will return all sequences from the source mould
Sepedonium ampullosporum.
