Genetic Codes

A Python library for working with the NCBI Genetic Codes

The NCBI Genetic Codes are central to working with alternate genetic codes. This Python tool kit includes a library that exposes the genetic codes so you can query a codon and get its variants or query a code and get its table.

The main function that you want to use has this signature:

amino_acid = translate(codon, translation_table=1, one_letter=False)

The codon is the codon that you want to translate as either an RNA (e.g. AUG) or DNA (e.g. ATG) sequence. The translation_table is your required translation table (see the NCBI website for valid tables), and one_letter is whether to return a three letter amino acid code (e.g. Met or Ter) or a one letter amino acid code (e.g. M or *).

The library provides other ways to access the genetic codes, and those are exemplified in the pytest files in tests/

Installation

You can install pygenetic_code with pip.
