Transsulfuration in archaebacteria.
The transfer of sulfur from methionine to cysteine in the archaebacteria Sulfolobus acidocaldarius and Halobacterium marismortui was studied by feeding 34S-labeled methionine to cells and measuring the incorporation of 34S into protein-bound cellular cysteine and methionine by mass spectrometry. It was found that, as are eucaryotes, both of these archaebacteria were able to convert the sulfur o...
متن کاملImmunological comparison of ribosomal proteins from archaebacteria.
Antisera were raised in rabbits against ribosomal proteins of Methanobacterium bryantii and used to analyze immunological relationships to ribosomes from other archaebacteria, from eubacteria, and from yeasts. Cross-reaction could be detected within the methanogens and with a member of the extreme halophiles; the degree of immunological similarity reflected the relationship delineated by 16S ri...
متن کاملLight sensitivity of methanogenic archaebacteria.
Representatives of four families of methanogenic archaebacteria (archaea), Methanobacterium thermoautotrophicum delta H, Methanobacterium thermoautotrophicum Marburg, Methanosarcina acetivorans, Methanococcus voltae, and Methanomicrobium mobile, were found to be light sensitive. The facultative anaerobic eubacteria Escherichia coli and Salmonella typhimurium, however, were tolerant of light whe...
متن کاملDihydrolipoamide dehydrogenase from halophilic archaebacteria.
Dihydrolipoamide dehydrogenase has been discovered in the halophilic archaebacteria for the first time. The enzyme from both classical and alkaliphilic halobacteria has been investigated. (1) The enzyme specifically catalysed the stoichiometric oxidation of dihydrolipoamide by NAD+. Enzymic activity was optimal at 2 M-NaCl and was remarkably resistant to thermal denaturation. (2) The relative m...
متن کاملPathogenic archaebacteria: do they not exist because archaebacteria use different vitamins?
Sir, Recently in these pages, Cavicchioli et al. addressed an interesting question, namely: do pathogenic archaebacteria exist? In themain, they cite evidence to establish the following points. (1)Noarchaebacteria haveyet been found tobeagents of disease. (2) Archaebacteria are sufficiently abundant in non-extreme environments as to provide them ample opportunity to infect animals and humans. (...
