Stufa


Definition:

  • (n.) A jet of steam issuing from a fissure in the earth.

Example Sentences:

Tufa


Definition:

  • () A soft or porous stone formed by depositions from water, usually calcareous; -- called also calcareous tufa.
  • () A friable volcanic rock or conglomerate, formed of consolidated cinders, or scoria.

Example Sentences:

  • (1) A trend towards a higher G+C content in fusA (gene encoding elongation factor (EF)-G) and tufA (gene encoding EF-Tu) in S. typhimurium is noted.
  • (2) The combination of tufA(Aa) and a rpsD12 ribosomal mutation is lethal at room temperature and the double-mutant strain has an elevated temperature optimum (42 degrees C) for growth rate, translation rate and nonsense suppression.
  • (3) Furthermore, the tufA mutation enhances the cellular growth rate of the rpsL mutant, whereas it decreases growth of strains with normal ribosomes.
  • (4) Previous work suggested that the tufA gene, encoding protein synthesis elongation factor Tu, was transferred from the chloroplast to the nucleus within the green algal lineage giving rise to land plants.
  • (5) The observations that introduction of a tufA(+) region makes the resistant strain sensitive to the antibiotic and that transduction of tufB1 into a recipient other than E. coli D22 yields kirromycin-sensitive progeny support these conclusions.
  • (6) Potential ribosome binding sites are located 58 and 32 positions upstream of the tufA and ORF206 start codon, respectively.
  • (7) We have replaced the ribosomal binding site (RBS) of the lacZ gene of E. coli by those of the maturation (A) gene of phage MS2 and that of the tufA gene.
  • (8) By examining heteroduplexes between restriction endonuclease-generated fragments of DNA containing the tufA, fus, and tufB genes, we have demonstrated that the fus and tufA genes are intimately related physically in one of two possible arrangements.
  • (9) The proof for the presence of tufA gene in pTUAl is based on the following observations: (1) ability of pTUAl DNA and is EcoRI fragments to direct synthesis of EF-Tu in a cell-free protein synthesizing system; and (2) RNA .
  • (10) It thus became possible to study the consequences for growth of tufA inactivation by insertion of bacteriophage Mu.
  • (11) Genetic data suggest that pTu is the product of the tufA and tufB genes.
  • (12) Therefore, phenotypic expression of kirromycin resistance in vivo appears to be only possible if the EF-Tu mutant lacks an active tufA gene, a property likely to be inherited from the parental D22 strain.
  • (13) Facebook Twitter Pinterest Juvenile hart’s tongues, among mosses embedded in tufa.
  • (14) Sequence analysis revealed an ORF of 99 amino acids (including the N-terminal processed methionine) at a position 477 bp from the 3' end of tufA but on the opposite strand.
  • (15) We conclude the following: (a) The tufA and tufB messengers have different half lives (3.0 and 2.4 min, respectively).
  • (16) Filter hybridizations reveal a chloroplast tufA gene in all Ulvophyceae and Chlorophyceae and in some but not all Charophyceae.
  • (17) The G domain of elongation factor Tu (EF-Tu), representing the N-terminal half of the factor according to its three-dimensional model traced at high resolution, has been isolated by genetic manipulation of tufA and purified to homogeneity.
  • (18) The water is sharply alkaline, with a pH value of over nine, and thanks in part to the water's purity – no phosphates here – the formation of tufa continues on the Lathkill when it has ceased on most other rivers.
  • (19) The tufA gene, one of two genes in Escherichia coli encoding elongation factor Tu (EF-Tu), was cloned into a ColE1-derived plasmid downstream of the lac promoter-operator.
  • (20) A deletion mutant of a plasmid born Escherichia coli tufA gene, which codes for a truncated elongation factor Tu comprising domains 2 and 3, has been constructed by genetic engineering.
