Elucidation of Bioactive compounds in flower extracts of Camellia sinensis by HPLC-DAD-MS/MS and their inhibitory effects on replicative bacterial DNA polymerases
(Elsevier, 2022)
Camellia sinensis L. (C. sinensis) is an economically valuable crop whose leaves are used to produce tea. Tea flowers extracts (TFE) have been tested for their DNA polymerase inhibitory effect experimentally and in silico. ...
Effect of mazEF, higBA and relBE toxin-antitoxin systems on antibiotic resistance in Pseudomonas aeruginosa and Staphylococcus isolates
(Med Coll Malawi, 2018)
Background A toxin-antitoxin (TA) system is a set of two or more closely linked genes that are encoded as a poison and a corresponding antidote on a protein. in typical bacterial physiology, an antitoxin binds to a toxin ...
Investigation of common chemical components and inhibitory effect on GES-type beta-lactamase (GES22) in methanolic extracts of Algerian seaweeds
(Academic Press Ltd- Elsevier Science Ltd, 2019)
This study aimed to investigate the total phenolic content (TPC), the identification of the common compounds by HPLC-ESI-MS and HPLC-ESI-MS-TOF and the inhibitory effects against class A-type beta-lactamase (GES-22 variant, ...
Molecular characterization of antibiotic resistant Escherichia coli strains isolated from tap and spring waters in a coastal region in Turkey
(2007)
A hundred and seventeen antibiotic-resistant Escherichia coli strains were isolated from public tap and spring waters which were polluted by fecal coliforms. There were no significant differences between two water sources ...
Cloning, expression, purification and characterization of fructose-1,6-bisphosphate aldolase from Anoxybacillus gonensis G2
(2007)
The fructose-1,6-bisphosphate aldolase gene from the thermophilic bacterium, Anoxybacillus gonensis G2, was cloned and sequenced. Nucleotide sequence analysis revealed an open reading frame coding for a 30.9 kDa protein ...
Comparison of DIG-11-dUTP utilization by Geobacillus caldoxylosilyticus TK4, Mycobacterium tuberculosis and Escherichia coli DNA polymerases
(Springer Link, 2010)
DNA polymerases are used for many applications and we comparatively investigated DNA synthesis activity of DNA polymerase I enzymes of Geobacilluscaldoxylosilyticus TK4, Escherichia coli and Mycobacterium tuberculosis with ...
A new DNA polymerase i from Geobacillus caldoxylosilyticus TK4: Cloning, characterization, and mutational analysis of two aromatic residues
(Springer, 2009)
DNA polymerase I gene was cloned and sequenced from the thermophilic bacterium Geobacillus caldoxylosilyticus TK4. The gene is 2,634 bp long and encodes a protein of 878 amino acids in length. The enzyme has a molecular ...
Class 1 and class 2 integrons and plasmid-mediated antibiotic resistance in coliforms isolated from ten rivers in northern Turkey
(2009)
We aimed to determine the molecular mechanisms of antibiotic resistance in coliforms isolated from ten rivers in northern region of Turkey. A total of 183 isolates were tested for antimicrobial susceptibility by disk ...
Prevalence of integrons and a new dfrA17 variant in Gram-negative bacilli which cause community-acquired infections
(Wiley, 2010)
A hundred and eleven Gram-negative bacilli from community-acquired infections were characterized by antimicrobial susceptibility testing, screened for class 1 and 2 integrons, and statistically evaluated for the association ...
Characterization of tetracycline resistance genes in tetracycline-resistant Enterobacteriaceae obtained from a coliform collection
(Springer, 2010)
Tetracycline resistance has been used as the key determinant to monitor resistance genes in natural environments such as rivers, lakes or seawater. The aim of this study was evaluate the frequency of tetA, tetB, tetC, tetD ...
