Abstract:Inteins are self-splicing protein elements found in viruses and all three domains of life. How the DNA encoding these selfish elements spreads within and between genomes is poorly understood, particularly in eukaryotes where inteins are scarce. Here, we show that the nuclear genomes of three strains of
Anaeramoeba
encode between 45 and 103 inteins, in stark contrast to four found in the most intein-rich eukaryotic genome described previously. The
Anaeramoeba
