How does a protein sound like: Converting amino acid sequences into music, and back
We have developed a system that translates amino acid sequences into musical notes, reflecting the specific characteristics of those sequences. Unlike most other methods of converting amino acid sequences into musical compositions, our approach enables the same algorithm to be used for converting musical passages back into proteins without relying on their nucleotide sequence encoding. This is accomplished through the use of a doublet degenerate code to encode musical notes, chords, and pauses. As a result, one can select from several dozen options to create an amino acid sequence with specified properties.
