Abstract
We have studied the single rRNA gene cluster from the Archaeon, Pyroco ccus furiosus. This isolate grows optimally at 100-degrees-C and is th us a hyperthermophile. In P. furiosus, transcription of 16S rRNA is su bject to regulation over a 7.5-fold range in response to a 20-fold inc rease in growth rate. The single cluster encoding the 16S and 23S rRNA genes of P. furiosus was cloned and the 1.9 kb region upstream of the 16S rRNA gene was sequenced.
