Discovery and characterization of a thermostable bacteriophage RNA ligase homologous to T4 RNA ligase 1.

Thermophilic viruses represent a novel source of genetic material and enzymes with great potential for use in biotechnology. We have isolated a number of thermophilic viruses from geothermal areas in Iceland, and by combining high throughput genome sequencing and state of the art bioinformatics we have identified a number of genes with potential use in biotechnology. We have also demonstrated the existence of thermostable counterparts of previously known bacteriophage enzymes.
