# 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
- 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.
