The nucleotide sequence of the tRNAMMet from the archaebacterium Thermoplasma acidophilum.
Using in vitro labelling techniques, a tRNAMMet from Thermoplasma acidophilum, a member of the Archaebacteriae, has been shown to have the sequence: pGCCGGG Gs4UGGCUCANCUGGAGGAGC m2(2)GCCGGACmUCAUt6AAUCCGGAGGUCUCGGG psi psi CmGAUCCCCGAUCCCGGCACCAOH. Despite the small genome size of this non-parasitic organism, eight modified nucleosides are present, one of which is typically eubacterial, one of which is typically eukaryotic and some of which appear to be unique to the archaebacteria. There is no close sequence homology between this tRNA and that of any other methionine tRNA so far sequenced (less than 70%) but it has almost 90% homology with the nucleotide sequence proposed by Eigen and Oswatitsch for the ancestral quasi-species.
