Angewandte Chemie, EarlyView.Three‐component thio‐ and carbo‐boration reactions to form functionalised benzoxaborinines and benzazaborinines are reported. The nucleophile scope includes thioethers, thiols, and (hetero)arenes. Mechanistic studies revealed a disparity between thioboration using thioethers and using thiols.

Genomic analysis of bifunctional Class C-Class D β-lactamases in environmental bacteria
Memorias do Instituto Oswaldo Cruz, 2018 β-lactamases, which are found in several bacterial species and environments, are the main cause of resistance to β-lactams in Gram-negative bacteria. In 2009, a protein (LRA-13) with two β-lactamase domains (one class C domain and one class D domain) was

Could β-Lactam Antibiotics Block Humoral Immunity?
Frontiers in Immunology, 2021 It has been reported that treatment with β-lactam antibiotics induces leukopenia and candidemia, worsens the clinical response to anticancer immunotherapy and decreases immune response to vaccination.

Nucleotide sequence of the gene encoding the active-site serine β-lactamase fromStreptomyces cacaoi [PDF]
FEMS Microbiology Letters, 1988 Abstract The gene encoding the extracellular active-site serine β-lactamase of Streptomyces cacaoi previously cloned into Streptomyces lividans , has the information for the synthesis of a 303 amino-acid precursor. The β-lactamase as excreted by the host S.

Identification of Family Specific Fingerprints in β-Lactamase Families
The Scientific World Journal, 2014 Beta-lactamases are a superfamily of enzymes which degrade the β-lactam class of antibiotics. They are produced endogenously by the bacterial cells, which when exposed to the β-lactam class of antibiotics inactivate them by cleaving the β-lactam ring ...

Periodontology 2000, EarlyView., 2023 Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

Microbiome, 2017 Background Metallo-β-lactamases are bacterial enzymes that provide resistance to carbapenems, the most potent class of antibiotics. These enzymes are commonly encoded on mobile genetic elements, which, together with their broad substrate spectrum and ...
