Chemotaxis in the archaebacterium Methanococcus voltae.
The archaebacterium Methanococcus voltae, was shown to be chemotactic. Acetate, isoleucine, and leucine were identified as attractants; whereas histidine was not an attractant. A motile, generally nonchemotactic mutant was isolated.
متن کاملBiosynthesis of selenium-modified tRNAs in Methanococcus vannielii.
Selenium-containing nucleosides are natural components of several tRNA species in Methanococcus vannielii. In the present study, the incorporation of selenium from 75SeO3(2-) into these macromolecules was investigated in sonic extracts of M. vannielii. Nucleoside analysis of the 75Se-labeled tRNAs from these in vitro reaction mixtures demonstrated that the selenium was present in 75Se-labeled n...
متن کاملSolution NMR structure of selenium-binding protein from Methanococcus vannielii.
Selenium is an important nutrient. The lack of selenium will suppress expression of various enzymes that will lead to cell abnormality and diseases. However, high concentrations of free selenium are toxic to the cell because it adversely affects numerous cell metabolic pathways. In Methanococcus vannielii, selenium transport in the cell is established by the selenium-binding protein, SeBP. SeBP...
متن کاملHeat shock response of the archaebacterium Methanococcus voltae.
The general properties of the heat shock response of the archaebacterium Methanococcus voltae were characterized. The induction of 11 heat shock proteins, with apparent molecular weights ranging from 18,000 to 90,000, occurred optimally at 40 to 50 degrees C. Some of the heat shock proteins were preferentially enriched in either the soluble (cytoplasm) or particulate (membrane) fraction. Altern...
متن کاملMethanococcus vannielii: ultrastructure and sensitivity to detergents and antibiotics.
Methanococcus vannielii is a strictly anaerobic motile coccus that possesses a tuft of flagellae. The cells are markedly sensitive to mechanical stress and are readily lysed by detergents, but the organism grows normally in media of low ionic strength. The absence of a typical cell wall, further suggested by resistance of M. vannielii to penicillin, cycloserine, and vancomycin, was confirmed by...
