The amino acid sequence in the value of /translation qualifier seems to be incorrect.

Last updated:2014.7.3.

The rule to translate nucleotide sequence into amino acid sequence is specified in accordance with agreements of International Nucleotide Sequence Database Collaboration.
The codon table using a CDS feature is specified in the value of /transl_table qualifier as a number of The Genetic Codes.

There are three points frequently misunderstood.

  • You should specify /organelle qualifier to assign correct genetic code for mitochondrion or chloroplast.
  • The initiation codon is M, Met, methyonine, not G or V.
        See Start codon and N-Formylmethionine
  • When an amino acid can be specified by two bases (i.e. degeneracy of codons), it will be outputted.

There are some exceptional cases, represented by RNA editing and so on.
