How Developers Can Use DNA Sequence Tools to Design Proteins for Precision Fermentation

A DEV Community article explains how software developers can work with DNA and protein data using Python and the Biopython library. It shows how a DNA sequence is translated into a chain of amino acids, with each letter representing one amino acid. Cow milk protein sequences such as beta-lactoglobulin and the caseins are described as publicly available through databases like UniProt and NCBI GenBank. The piece then outlines codon optimization, in which a gene is rewritten to use the codons a host organism favors while still encoding the same protein, and it notes that real tools weigh additional factors such as GC content and repeats.
