Genetic transformation of the extreme thermophile Thermus thermophilus and of other Thermus spp
TLDR
Competence was maintained throughout the growth phase, with the highest transformation frequencies at pH 6 to 9 and at 70 degrees C, and optimal transformation was obtained by the addition of a divalent cation (Ca2+ or Mg2+).
The Glutathione System of Aspergillus nidulans Involves a Fungus-specific Glutathione S-Transferase*
TLDR
Up-regulation of thioredoxin reductase, peroxiredoxins, catalases, and cytochrome c peroxidase in the glrA-deletion strain revealed interplay between the glutathione system and both the thiOREDoxin system and hydrogen peroxide defense mechanisms.
A prokaryotic gene cluster involved in synthesis of lysine through the amino adipate pathway: a key to the evolution of amino acid biosynthesis.
TLDR
This gene cluster was analogous in part to the present leucine and arginine biosyntheses pathways and is assumed to be one of the origins of lysine biosynthesis and could therefore become a key to the evolution of amino acid biosynthesis.
Glutathione Reductase/Glutathione Is Responsible for Cytotoxic Elemental Sulfur Tolerance via Polysulfide Shuttle in Fungi*
TLDR
Findings that GR-deficient mutants derived from Saccharomyces cerevisiae and Aspergillus nidulans reduced less sulfur and that their growth was hypersensitive to elemental sulfur indicated a wide distribution of the GR/glutathione system among fungi.
Isolation and Characterization of a New Quinoprotein Dehydrogenase, L-Sorbose/L-Sorbosone Dehydrogenase.
Gluconobacter oxydans DSM 4025 effectively oxidizes L-sorbose to 2-keto-L-gulonic acid (2 KGA), an industrial precursor of vitamin C. From this microorganism, we purified the enzyme involved in this
