CodonTransformer Dataset

A comprehensive compilation of 1,001,197 DNA and protein sequence pairs, sourced from 164 organisms across Eukaryotes, Bacteria, and Archaea. This dataset provides a rich resource for various computational biology and bioinformatics applications such as studying gene sequences, codon usage, and protein expression across diverse species.

Dataset Contents

  • 1,001,197 DNA-protein sequence pairs
  • Sequences from 164 organisms, including:
    • Eukaryotes: Homo sapiens, Arabidopsis thaliana, Caenorhabditis elegans, Danio rerio, Drosophila melanogaster, Mus musculus, Saccharomyces cerevisiae, Chlamydomonas reinhardtii, Nicotiana tabacum
    • Bacteria: Various Enterobacteriaceae species including Escherichia coli
    • Archaea: Thermococcus barophilus, Sulfolobus solfataricus
    • Chloroplast genomes: Chlamydomonas reinhardtii, Nicotiana tabacum

Data Collection and Preprocessing

  • Source: NCBI resources
  • Original Format: Gene or CDS (Coding Sequence)
  • Protein Sequences: Translated using NCBI Codon Tables
  • Quality Control:
    • DNA sequences divisible by three in length
    • Start with a start codon
    • End with a single stop codon

Dataset Structure

Each entry contains:

  • DNA sequence
  • Corresponding protein sequence
  • Gene and organism information

Uses and Applications

This dataset is valuable for various research areas and applications, including:

  • Comparative genomics
  • Codon usage analysis
  • Protein expression optimization
  • Synthetic biology and genetic engineering
  • Machine learning models in bioinformatics

It has been used to train the CodonTransformer model for codon optimization tasks.
