Halophilic enzymes in cell-free extracts of Halobacterium salinarium.
Cells of the obligately halophilic bacterium Halobacterium salinarium have been shown to contain high concentrations of sodium and potassium chloride (Christian and Ingram, J. Gen. Microbiol. 20:27, 1959; Christian and Waltho, Biochim. Biophys. Acta 65:506, 1962). Enzymes extracted from this organism require up to 25% NaCl for optimal activity (Baxter and Gibbons, Can. J. Microbiol. 2:599, 1956...
متن کاملArginine metabolism in Halobacterium salinarium, an obligately halophilic bacterium.
Dundas, Ian E. D. (University of Illinois, Urbana), and H. Orin Halvorson. Arginine metabolism in Halobacterium salinarium, an obligately halophilic bacterium. J. Bacteriol. 91:113-119. 1966.-Arginine was shown to be essential for growth of Halobacterium salinarium strain 1 in a chemically defined medium. Citrulline was the only compound which could substitute for arginine without affecting gro...
متن کاملDihydrofolate reductase of the extremely halophilic archaebacterium Halobacterium volcanii. The enzyme and its coding gene.
Halobacterium volcanii mutants that are resistant to the dihydrofolate reductase inhibitor trimethoprim contain DNA sequence amplifications. This paper describes the cloning and nucleic acid sequencing of the amplified DNA sequence of the H. volcanii mutant WR215. This sequence contains an open reading frame that codes for an amino acid sequence that is homologous to the amino acid sequences of...
متن کاملUnusual evolution of a superoxide dismutase-like gene from the extremely halophilic archaebacterium Halobacterium cutirubrum.
The archaebacterium Halobacterium cutirubrum contains a single detectable, Mn-containing superoxide dismutase, which is encoded by the sod gene (B. P. May and P. P. Dennis, J. Biol. Chem. 264:12253-12258, 1989). The genome of H. cutirubrum also contains a closely related sod-like gene (slg) of unknown function that has a pattern of expression different from that of sod. The four amino acid resi...
متن کاملIsolation of an ftsZ homolog from the archaebacterium Halobacterium salinarium: implications for the evolution of FtsZ and tubulin.
We have isolated a homolog of the cell division gene ftsZ from the extremely halophilic archaebacterium Halobacterium salinarium. The predicted protein of 39 kDa is divergent relative to eubacterial homologs, with 32% identity to Escherichia coli FtsZ. No other eubacterial cell division gene homologs were found adjacent to H. salinarium ftsZ. Expression of the ftsZ gene region in H. salinarium ...
