Feature | CDS |
Definition | coding sequence; sequence of nucleotides that corresponds with the sequence of amino acids in a protein (location includes stop codon); feature includes amino acid conceptual translation. |
Optional Qualifiers | /artificial_location="[artificial_location_value]" /circular_RNA /codon_start=<1 or 2 or 3> /db_xref="<database>:<identifier>" /EC_number="text" /exception="[exception_value]" /experiment="[CATEGORY:]text" /function="text" /gene="text" /gene_synonym="text" /inference="[CATEGORY:]TYPE[ (same species)][:EVIDENCE_BASIS]" /locus_tag="text" (single token) /map="text" /note="text" /number=unquoted text (single token) /old_locus_tag="text" (single token) /operon="text" /product="text" /protein_id="<identifier>" /pseudo /pseudogene="TYPE" /ribosomal_slippage /standard_name="text" /translation="text" /transl_except=(pos:<location>,aa:<amino_acid>) /transl_table =<integer> /trans_splicing |
Comments | /codon_start has valid value of 1 or 2 or 3, indicating the offset at which the first complete codon of a coding feature can be found, relative to the first base of that feature; /transl_table defines the genetic code table used if other than the universal genetic code table; genetic code exceptions outside the range of the specified tables is reported in /transl_except qualifier; /protein_id consists of a stable ID portion (from the end of 2018 new accessions may be extended to a 3+7 accession format with 3 position letters and 7 numbers; existing data before the end of 2018 uses a 3+5 format) plus a version number after the decimal point; when the protein sequence encoded by the CDS changes, only the version number of the /protein_id value is incremented; the stable part of the /protein_id remains unchanged and as a result will permanently be associated with a given protein; |
