Ribosomes from the extreme thermophile Thermus thermophilus are capable of translation in a coupled transcription-translation system derived from Escherichia coli. At 45degreeC, T.thermophilus ribosomes translate at apprx25-30% of the maximal rate of E.coli ribosomes, and synthesize full-length protein. T.thermophilus and E.coli subunits can be combined to effect translation, with the spectrum of proteins produced depending upon the source of the 30S subunit.
