Boron stress activates the general amino acid control mechanism and inhibits protein synthesis
Uluışık, İrem; Kaya, Alaattin; Fomenko, Dmitri E.; Karakaya, Hüseyin Çağlar; Carlson, Bradley A.; Gladyshev, Vadim N.; Koç, Ahmet (Public Library of Science, 2011-11)Boron is an essential micronutrient for plants, and it is beneficial for animals. However, at high concentrations boron is toxic to cells although the mechanism of this toxicity is not known. Atr1 has recently been identified ... -
Characterization of a cDNA from Beta maritima that confers nickel tolerance in yeast
Bozdaǧ, Gönensin Ozan; Kaya, Alaattin; Koç, Ahmet; Noll, Gundula A.; Prüfer, Dirk; Karakaya, Hüseyin Çaǧlar (Elsevier, 2014-04)Nickel is an essential micronutrient due to its involvement in many enzymatic reactions as a cofactor. However, excess of this element is toxic to biological systems. Here, we constructed a cDNA library from Beta maritima ... -
Compartmentalization and regulation of mitochondrial function by methionine sulfoxide reductases in yeast
Kaya, Alaattin; Koç, Ahmet; Lee, Byung Cheon; Fomenko, Dmitri E.; Rederstorff, Mathieu; Krol, Alain; Lescure, Alain; Gladyshev, Vadim N. (American Chemical Society, 2010-10)Elevated levels of reactive oxygen species can damage proteins. Sulfur-containing amino acid residues, cysteine and methionine, are particularly susceptible to such damage. Various enzymes evolved to protect proteins or ... -
Functional analysis of free methionine-R-sulfoxide reductase from saccharomyces cerevisiae
Le, Dung Tien; Lee, Byung Cheon; Marino, Stefano M.; Zhang, Yan; Fomenko, Dmitri E.; Kaya, Alaattin; Hacıoğlu, Elise; Kwak, Geun-Hee; Koç, Ahmet; Kim, Hwa-Young; Gladyshev, Vadim N. (American Society for Biochemistry and Molecular Biology, 2009-02)Methionine sulfoxide reductases (Msrs) are oxidoreductases that catalyze thiol-dependent reduction of oxidized methionines. MsrA and MsrB are the best known Msrs that repair methionine S-sulfoxide (Met-S-SO) and ... -
Genome-wide identification of genes that play a role in boron stress response in yeast
Uluışık, İrem; Kaya, Alaattin; Ünlü, Ercan Selçuk; Avşar, Kadir; Karakaya, Hüseyin Çağlar; Yalçın, Talat; Koç, Ahmet (Elsevier BV., 2011-02)Boron is an essential micronutrient for plants and it is either necessary or beneficial for animals. Studies identified only few genes related to boron metabolism thus far and details of how boron is imported into cells ... -
Identification of a novel system for boron transport: Atr1 is a main boron exporter in yeast
Kaya, Alaattin; Karakaya, Hüseyin Çağlar; Fomenko, Dmitri E.; Gladyshev, Vadim N.; Koç, Ahmet (American Society for Microbiology, 2009-07)Boron is a micronutrient in plants and animals, but its specific roles in cellular processes are not known. To understand boron transport and functions, we screened a yeast genomic DNA library for genes that confer resistance ... -
Identification of genes that play roles in boron metabolism/
Kaya, Alaattin (Izmir Institute of Technology, 2008)Boron, is an essential microelement that plays a role in plant and animal development. However, an excess amount of boron is toxic for both types of organisms.The yeast Saccharomyces cerevisiae is an ideal model organism ... -
Proteomic changes during boron tolerance in barley (Hordeum vulgare) and the role of vacuolar proton-translocating ATPase subunit E
Atik, Ahmet Emin; Bozdağ, Gönensin Ozan; Akıncı, Ersin; Kaya, Alaattin; Koç, Ahmet; Yalçın, Talat; Karakaya, Hüseyin Çağlar (TÜBİTAK, 2011)Boron is an essential micronutrient for plants and animals; however, it can be toxic when present at high concentrations. The purpose of this study was to understand the mechanisms of boron tolerance in the Turkish barley ... -
Thiol peroxidase deficiency leads to increased mutational load and decreased fitness in saccharomyces cerevisiae
Kaya, Alaattin; Lobanov, Alexey V.; Gerashchenko, Maxim V.; Koren, Amnon; Fomenko, Dmitri E.; Koç, Ahmet; Gladyshev, Vadim N. (Genetics Society of America, 2014-11)Thiol peroxidases are critical enzymes in the redox control of cellular processes that function by reducing low levels of hydroperoxides and regulating redox signaling. These proteins were also shown to regulate genome ...
