“…As determined by 16s ribosomal ribonucleic acid cataloging, S . acidocaldarius DSM 639T and S. solfataricus DSM 1616T show a similarity coefficient of only 0.41 (40), indicating a large phylogenetic difference between these two species of the same genus. However, no further distinguishing taxonomic markers are present now to justify their placement in different genera.…”

“…Within the thermoacidophiles there are three orders, Sulpholobus, Thermoplasma and Thermoproteus, although it is thought that Thermoplasma is phylogenetically distinct from the other two thermophiles [2]. Indeed, it has been suggested that Sulpholobus and Thermoproteus may constitute a separate kingdom, the Eocyta [3].…”

It has been found that the thermoacidophilic archaebacterium, Thermoplasma acidophilum, can metabolise glucose via a modified Entner-Doudoroff pathway involving non-phosphorylated intermediates. Pyruvate and glyceraldehyde are the first products, the glyceraldehyde then being further metabolised to a second molecule of pyruvate via 2-phosphoglycerate. Intermediates of this pathway have been identified by enzymic analysis or by thin-layer chromatography and the individual enzymes involved have been assayed and their kinetic parameters determined. Comparisons are made with the pathways of glucose metabolism in other archaebacteria. Archaebacteria (Thermoplasma)Entner-Doudoroffpathway Glucose metabolism

“…In bacteria these sites are C*-967 in h31 and U*-1498 in the center of the decoding region in h44. An exception to the bacterial uniqueness of a modified C-967 appears to occur in the archaeon Thermoproteus tenax (Woese et al 1984). The position 967 modification is reported to be m 5 C in all four cases in which the nucleoside structure has been established (E. coli, Thermus, Thermotoga, and Proteus).…”

“…Interestingly, C-1404 has been reported as modified but with unknown structure in the RNase T1 SSU maps of five bacteria (Rozenski and McCloskey 2005), and two archaea, H. volcanii (Gupta et al 1983) and S. solfataricus (Woese et al 1984). C-1404 pairs with essentially universal G-1497 (Cannone et al 2002) near the top of h44.…”

Post-transcriptional modifications of RNA are nearly ubiquitous in the principal RNAs involved in translation. However, in the case of rRNA the functional roles of modification are far less established than for tRNA, and are subject to less knowledge in terms of specific nucleoside identities and their sequence locations. Post-transcriptional modifications have been studied in the SSU rRNA from Thermotoga maritima (optimal growth 80°C), one of the most deeply branched organisms in the Eubacterial phylogenetic tree. A total of 10 different modified nucleosides were found, the greatest number reported for bacterial SSU rRNA, occupying a net of ;14 sequence sites, compared with a similar number of sites recently reported for Thermus thermophilus and 11 for Escherichia coli. The relatively large number of modifications in Thermotoga offers modest support for the notion that thermophile rRNAs are more extensively modified than those from mesophiles. Seven of the Thermotoga modified sites are identical (location and identity) to those in E. coli. An unusual derivative of cytidine was found, designated N-330 (M r 330.117), and was sequenced to position 1404 in the decoding region of the rRNA. It was unexpectedly found to be identical to an earlier reported nucleoside of unknown structure at the same location in the SSU RNA of the archaeal mesophile Haloferax volcanii.
