skbio.sequence.RNA.translate#

RNA.translate(genetic_code=1, *args, **kwargs)[source]#

Translate RNA sequence into protein sequence.

Parameters:

genetic_codeint, GeneticCode, optional: Genetic code to use in translation. If int, used as a table ID to look up the corresponding NCBI genetic code.
argstuple: Positional arguments accepted by GeneticCode.translate.
kwargsdict: Keyword arguments accepted by GeneticCode.translate.

Returns:

Protein: Translated sequence.

Notes

RNA sequence’s metadata are included in the translated protein sequence. Positional metadata are not included.

Examples

Translate RNA into protein using NCBI’s standard genetic code (table ID 1, the default genetic code in scikit-bio):

>>> from skbio import RNA
>>> rna = RNA('AUGCCACUUUAA')
>>> rna.translate()
Protein

Stats:
    length: 4
    has gaps: False
    has degenerates: False
    has definites: True
    has stops: True

Translate the same RNA sequence using a different NCBI genetic code (table ID 3, the yeast mitochondrial code) and specify that translation must terminate at the first stop codon:

>>> rna.translate(3, stop='require')
Protein

    length: 3

    has degenerates: False
