Reverse Translate

How to reverse translate a protein

  1. Paste one or more protein sequences.
  2. Choose degenerate IUPAC codons, or paste a codon usage table to use the most common codon for each amino acid.
  3. Choose the genetic code. Copy output or Download saves the result.

Frequently asked questions

What is a degenerate reverse translation?

Each amino acid becomes one codon written with IUPAC codes that covers all of its codons, for example GCN for alanine. For leucine, serine and arginine, whose codons differ in more than one position, that codon also covers some codons of other amino acids.

Where do I get a codon usage table?

Run coding sequences from your organism through the Codon Usage tool and paste its output here.

Is my sequence uploaded?

No. Everything runs in your browser, so your sequences never leave your device.
