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.

Periodontal microbiology and microbial etiology of periodontal diseases: Historical concepts and contemporary perspectives

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.

Approachable Synthetic Methodologies for Second-Generation β-Lactamase Inhibitors: A Review

Pharmaceuticals
Some antibiotics that are frequently employed are β-lactams. In light of the hydrolytic process of β-lactamase, found in Gram-negative bacteria, inhibitors of β-lactamase (BLIs) have been produced.

Comparative Metagenomics and Network Analyses Provide Novel Insights Into the Scope and Distribution of β-Lactamase Homologs in the Environment

Frontiers in Microbiology, 2019
The β-lactams are the largest group of clinically applied antibiotics, and resistance to these is primarily associated with β-lactamases. There is increasing understanding that these enzymes are ubiquitous in natural environments and henceforth ...

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

Periodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...

Normalization of Transfection Efficiency Using the β-Lactamase Gene of the pGL3 Luciferase Vector in Primary Anterior Pituitary Cells

BioTechniques, 2002
The β-galactosidase reporter gene is commonly used as a control for transfection efficiency in the promoter reporter assay system. While investigating vasoactive intestinal peptide response elements in the promoter of the prolactin gene, we found that ...

Discovery of H2 Receptor Antagonists as Colistin Enhancers by Targeting Acid Stress Response

Advanced Science, EarlyView.
This study identifies YqgB as a key target for restoring colistin susceptibility in mcr‐positive pathogens under acidic conditions by remodeling phospholipid composition and reducing LPS modification. Deep learning‐based screening reveals H2 receptor antagonists as novel colistin adjuvants. Further investigations indicate that ranitidine and famotidine
