pH-dependent quenching of the fluorescence of tryptophan residues in class A beta-lactamase from E. coli (TEM-1).

چکیده
We performed an investigation of the pH-dependent quenching of the fluorescence of tryptophan residues of TEM-1 beta-lactamase from E. coli by uncharged and charged quenchers. pH-dependent Stern-Volmer constants (Ksv/pH) of tryptophan residues allowed us to determine subtle but discrete structurally and functionally important processes.

Antibiotic Resistance Pattern and Genotype of Beta-Lactamase Producing Escherichia coli Isolates from Urinary Tract Infections in Zabol-Souteast of Iran
Introduction: Extended spectrum beta-lactamase (ESBL) producing Escherichia coli generate a major problem for clinical therapeutics and epidemiological study. The incidence of ESBL producing strains among clinical isolates has been steadily increasing during the past few years, and remains an important cause of failure of therapy with cephalosporins. The aim of this study was to determine the a...

Background & Aims: One of the most common causes of bacterial resistance to beta-lactam antibiotics is beta-lactamase producing. The aim of this study was to compare the antibiotic resistance of urinary Escherichia coli (E. coli) isolates producing CTX-M and TEM type beta-lactamases, and to determine the strains with co-resistance to multiple antibiotics in Mashhad, Iran. Methods: E. coli b...

Abstract Background and Objective: In the past, most strains of E. coli were susceptible to a wide range of antimicrobial agents, but this situation is now changed by indiscriminate use of antibiotics. Ceftriaxone and Ceftazidime are the most current antibiotics used for Enterobacteriaceae infections in hospitals. The aim of this study was to determine antimicrobial resistance of Escherichia co...

Background: Escherichia coli (E.coli) bacteria are member of Enterobacteriaceae which are one of the common causes of urinary tract infections. Beta-lactamase enzymes are important factors for antibiotic resistance of beta-lactam family in gram-negative bacteria. According to increasing rate of urinary tract infections due to antibiotic resistant E. coli, the aim of this study was to study the ...
