Qualifier
 |
codon |
| Definition |
specifies a codon which is different from any found in the reference genetic code
|
| Value Format |
(seq:"codon-sequence",aa:<amino_acid>) where
"codon-sequence" contains the bases of the codon and <amino_acid> is
the abbreviation for the translated amino acid, the abbreviation
for a modified unusual amino_acids from section 7.5,
or the word OTHER
|
| Example |
/codon=(seq:"ttt", aa:Leu) |
| Comment |
used to specify unusual genetic codes, organellar codes, etc, that are different from the "normal" code for the organism;
the codon specified by "seq" codes for the amino acid or stop
codon specified by "aa";
the codon that is specified is used throughout the CDS;
amino acids that are not on the controlled vocabulary list can be
annotated by using "aa:OTHER" as the amino acid designation, and
by giving the name of the residue in a /note qualifier;
only nucleotides a, g, c or t can be used in "codon-sequence";
multiple /codon qualifiers should be used to describe ambiguous
nucleotides.
