Tóm tắt

The susceptibility of Thermoplasma acidophilum (an extremely acidophilic, moderately thermophilic, wall-less sulphur-oxidizing archaebacterium) to 50 ribosome-specific inhibitors of polypeptide elongation was surveyed using efficient poly(U)-and poly(UG)-directed cell-free systems and comparable reference systems derived from eubacterial (Bacillus stearothermophilus, Escherichia coli) and eukaryotic (Saccharomyces cerevisiae) species. Under optimum temperature (58° C) and ionic conditions for polypeptide synthesis Thermoplasma ribosomes are only sensitive to the 70 S/80 S ribosome-directed aminoglycoside neomycin, and to five 80 S ribosome-directed inhibitors all of which (α-sarcin, mitogillin, restrictocin, dianthin and gelonin) impair the functioning of the large (60 S) ribosomal subunit. Sensitivity of the three structurally related compounds α-sarcin, mitogillin and restrictocin and susceptibility to neomycin place Thermoplasma ribosomes between those of Sulfolobus solfataricus (only sensitive to α-sarcin) and Methanococcus vannielli (sensitive to α-sarcin, mitogillin, restrictocin and neomycin but also affected by a variety of 70 S ribosome-directed drugs). The phylogenetic significance of the greatly diversified antibiotic sensitivity spectra displayed by archaebacteria in general, as opposed to the uniform ones exhibited by eubacteria and eukaryotes, is discussed.
