A helicase of archaeal phylogeny named HepA is encoded in the genome of all the Thermus spp. so far sequenced. As its archaeal homologues, HepA forms hexameric rings with a central pore able to accommodate single stranded DNA. Mutants without this protein show high sensitivity to UV radiations and are unable to grow at high temperatures. These data support that acquisition of this archaeal gene has been fundamental for the adaptation of Thermus spp. to hyperthermal environments. View the paper
