Clinical and Research Journal in Internal Medicine, 2021 Background: β-lactamase is an enzyme that plays a role in the occurrence of antibiotic resistance against Methicillin-resistant Staphylococcus aureus (MRSA) bacteria. Viscosin is a lipopeptide biosurfactant produced by the Pseudomonas group bacteria.

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 ...

Some aspects of general characteristic and classification of bacterial β-lactamases
Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2009 Main structural and functional groups of bacterial β-lactamases are cited in the data review. Modern systems of classification, which was based on spectra of activity, sensitivity to inhibitors and peculiarities of molecular structure are described.

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.

Fungal Lactamases: Their Occurrence and Function
Frontiers in Microbiology, 2017 Fungi are absorptive feeders and thus must colonize and ramify through their substrate to survive. In so doing they are in competition, particularly in the soil, with myriad microbes.

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.
