Yanmış, Derya; Karaoğlu, Hakan; Çolak, Dilşat Nigar; Sal, Fulya Ay; Çanakcı, Sabriye; Belduz, Ali Osman (Tubitak Scientific & Technical Research Council Turkey, 2014)The xylA gene encoding xylose isomerase from Anoxybacillus gonensis G2(T) has been cloned and successfully expressed in E. coli. Xylose isomerase was purified 10.98-fold by heat-shock and sequential column chromatography ... -
Cloning and determination of kinetic activity of thermophilic GCH-I from anoxybacillus flavithermus DSM 2641T
Phenylketonuria (PKU) is a disease caused by phenylalanine hydroxylase enzyme deficiency in newborn infants and is the most important cause of treatable mental retardation. One of the causes of the disease comes from the ... -
Cloning, expression, and characterization of a novel CTP synthase gene from Anoxybacillus gonensis G2
Sandallı, Cemal; Saral, Ayşegül; Ülker, Serdar; Karaoğlu, Hakan; Beldüz, Ali Osman; Çiçek, Ayşegül Çopur (2014)The cytidine-5'-triphosphate (CTP) synthase (EC 6.4.3.2) gene (pyrG) was cloned and sequenced from the thermophilic bacterium Anoxybacillus gonensis G2 (Ago). The gene is 1590 bp in length and encodes a protein of 530 amino ... -
Distribution of beta-lactamase genes among carbapenem-resistant klebsiella pneumoniae strains isolated from patients in Turkey
Iraz, Meryem; Düzgün, Azer Özad; Sandallı, Cemal; Doymaz, Mehmet Ziya; Akkoyunlu, Yasemin; Saral, Ayşegül; Peleg, Anton Y.; Özgümüş, Osman Birol; Beriş, Fatih Şaban; Karaoğlu, Hakan; Çiçek, Ayşegül Çopur (Korean Soc Laboratory Medicine, 2015)Background: the emergence of carbapenem-resistant Klebsiella pneumoniae poses a serious problem to antibiotic management.

DNA barcoding and species delimitation of the genus Oxynoemacheilus (Teleostei: Nemacheilidae) in Anatolia
Bektaş, Yusuf; Aksu, İsmail; Kaya, Cüneyt; Bayçelebi, Esra; Turan, Davut (Wiley, 2022)The DNA barcoding approach was used for the determination of evolutionary relationships and species delimitation of the genus Oxynoemacheilus (Teleostei: Nemacheilidae). The COI barcode region (615 bp amplicon) was used ... -
DNA barcoding of the genus Alburnoides Jeitteles, 1861 (Actinopterygii, Cyprinidae) from Anatolia, Turkey
Canoğlu, Halim; Aksu, İsmail; Turan, Davut; Bektaş, Yusuf (Pensoft Publishers, 2023)The present study investigated the ability of DNA barcoding to reliably identify the endemic freshwater species in Turkey, known as biodiversity hotspots. The barcode region (652 bp) of the mitochondrial cytochrome c oxidase ... -
