Deinococcus radiodurans
Genome structure:
The genome is composed of four circular molecules:
- Chromosome I = 2,648,638 base pairs (bp)
- Chromosome II = 412,348 base pairs
- A megaplasmid = 177,466 base pairs
- A plasmid = 45,704 base pairs
The genome contains 3187 open reading frames (ORFs), with an average size of 937 bp, representing 91% of the genome.Analysis of the genome shows that almost 30% of the total number of genes encodes proteins with regulatory functions (39 of 140) including: transcription factors, response regulators, and kinases are found on chromosome II and the megaplasmid.
