Divergent roles of CprK paralogues from Desulfitobacterium hafniense in activating gene expression [PDF]
, 2008 Gene duplication and horizontal gene transfer play an important role in the evolution of prokaryotic genomes. We have investigated the role of three CprK paralogues from the cAMP receptor protein-fumarate and nitrate reduction regulator (CRP-FNR) family ...

Scientifica, Volume 2025, Issue 1, 2025.The ban on the use of antibiotics in animal husbandry encourages an active search for highly effective alternatives with additional properties, one of which is ultrafine particles (UFP) of metallic nature. The objective of the presented work was to conduct a comprehensive analysis of newly synthesized UFP Co3O4 and Mn2O3, including determination of ...

Porphyrin and corrinoid mutants of Bacillus subtilis [PDF]
Journal of Bacteriology, 1977 Porphyrin auxotrophs of Bacillus subtilis can be divided into two groups. Strains belonging to the first group (hemA, hemB, or hemC) are not able to synthesize or metabolize porphobilinogen. These strains require cysteine, cystine, and methionine, respectively.

Environmental Microbiology, Volume 26, Issue 12, December 2024.We isolated a novel methanogenic archaeon, Methanosarcina hadiensis sp. nov. (TD41E1‐1), from Boom Clay pore water at a depth of 225 m. It exhibits unique characteristics compared to previously characterized Methanosarcina species, such as the inability to perform acetoclastic methanogenesis and the presence of extensive surface appendages.

Polyphenol Oxidase Activity on Guaiacyl and Syringyl Lignin Units
Angewandte Chemie, Volume 136, Issue 48, November 25, 2024.The conversion of lignin‐derived guaiacyl (G) and syringyl (S) compounds into methoxy‐ortho‐diphenols through oxidative ortho‐hydroxylation and ortho‐demethoxylation reactions catalyzed by novel fungal polyphenol oxidases (PPOs) is presented. The formation of o‐diphenols rather than reactive quinones can be steered by the addition of a reductant. These
