Anoxybacillus flavithermus WK1 AfCDA geninin klonlanması, ekspresyonu, saflaştırılması ve biyokimyasal karakteriasyonu
Eminoğlu, Ayşenur (Recep Tayyip Erdoğan Üniversitesi / Fen Bilimleri Enstitüsü / Biyoloji Anabilim Dalı, 2012)Karbohidrat esteraz 4 ailesi kitin, asetil ksilan ve peptidoglikan gibi polimerik substratları deasetile ederler. Son zamanlarda bu enzimlerden bazıları enzimolojik olarak karakterize edilmiştir. Termofilik bakterilerden ... -
Cloning, expression and biochemical characterization of a beta-carbonic anhydrase from the soil bacterium Enterobacter sp B13
Eminoğlu, Ayşenur; Vullo, Daniela; Aşık, Aycan; Çolak, Dilşat Nigar; Supuran, Claudiu T.; Çanakçı, Sabriye; Belduz, Ali Osman (Taylor & Francis Ltd, 2016)A recombinant carbonic anhydrase (CA, EC 4.2.1.1) from the soil-dwelling bacterium Enterobacter sp. B13 was cloned and purified by Co2+ affinity chromatography. Bioinformatic analysis showed that the new enzyme (denominated ... -
Cloning, purification and characterization of acetyl Xylane esterase from anoxybacillus flavithermus DSM 2641(T) with activity on low molecular-weight acetates
Eminoğlu, Ayşenur; Ülker, Serdar; Sandallı, Cemal (Springer, 2015)Family 4 carbohydrate esterases (CE-4) have deacetylate different forms of acetylated poly/oligosaccharides in nature. This family is recognized with a specific polysaccharide deacetylase domain assigned as NodB homology ... -
Deletion of the hfsB gene increases ethanol production in Thermoanaerobacterium saccharolyticum and several other thermophilic anaerobic bacteria
Eminoğlu, Ayşenur; Murphy, Sean Jean-Loup; Maloney, Marybeth; Lanahan, Anthony; Giannone, Richard J.; Hettich, Robert L.; Tripathi, Shital A.; Beldüz, Ali Osman; Lynd, Lee R.; Olson, Daniel G. (Bmc, 2017)Background: With the discovery of interspecies hydrogen transfer in the late 1960s (Bryant et al. in Arch Microbiol 59:20-31, 1967), it was shown that reducing the partial pressure of hydrogen could cause mixed acid ... -
Molecular and in silico cloning, identification, and preharvest period expression analysis of a putative cytochrome P450 monooxygenase gene from Camellia sinensis (L.) Kuntze (tea)
Cytochrome P450 monooxygenases are one of the largest heme-containing protein groups, and the majority of them catalyze hydroxylation reactions dependent on nicotinamide adenine dinucleotide phosphate and oxygen. Cytochrome ... -
Molecular diversity of Klebsiella pneumoniae clinical isolates: antimicrobial resistance, virulence, and biofilm formation
Kafa, Ayşe Hümeyra Taşkın; Aslan, Rukiye; Daştan, Sevgi Durna; Çelik, Cem; Hasbek, Mürşit; Eminoğlu, Ayşenur (Taylor & Francis Ltd., 2024)One of the mechanisms responsible for antibiotic resistance in Klebsiella pneumoniae is the enzymes produced by the bacteria; another important mechanism is the ability to form biofilm. In this study, antibiotic resistance, ... -
Sulfonamide inhibition studies of the beta-carbonic anhydrase from the newly discovered bacterium Enterobacter sp B13
Eminoğlu, Ayşenur; Vullo, Daniela; Aşık, Aycan; Çolak, Dilşat Nigar; Çanakcı, Sabriye; Beldüz, Ali Osman; Supuran, Claudiu T. (Pergamon-Elsevier Science Ltd, 2016)The genome of the newly identified bacterium Enterobacter sp. B13 encodes for a beta-class carbonic anhydrases (CAs, EC 4.2.1.1), EspCA. This enzyme was recently cloned, and characterized kinetically by this group (J. ... -
Survey for the pathogenic chytrid fungi batrachochytrium dendrobatidis and b. salamandrivorans on the caucasian salamander in northeastern Turkey
Altunışık, Abdullah; Gül, Serkan; Altunışık, Sümeyye; Eminoğlu, Ayşenur (Herpetological Conservation & Biology, 2021)Chytridiomycosis is an infectious disease of amphibians caused by either of two aquatic fungal pathogens, Batrachochytrium dendrobatidis (Bd) and B. salamandrivorans (Bsal). In this study, we carried out Bd and Bsal screening ...
