Glucose-6-phosphate dehydrogenase (G6PD, E.C. 1.1.1.49) is a ubiquitous enzyme that has a housekeeping role in all cells. This enzyme catalyzes the first step in the pentose phosphate pathway (PPP) converting glucose 6-phosphate (G6P) to produce 6- phosphogluconolactone with concomitant reduction of oxidized nicotinamide adenine dinucleotide phosphate (NADP+) to reduced nicotinamide adenine dinucleotide phosphate (NADPH). NADPH plays a key role in protecting cells against oxidative stress by regulating the level of reduced glutathione (GSH) (Hwang et al., 2018). In red blood cells (RBCs), G6PD is the only source for NADPH that is important for defense against oxidative stress If the NADPH concentration in the RBCs cannot be maintained, as in G6PD deficiency (G6PDD), the GSH levels fall and oxidative damage occurs which eventually resulting in hemolytic anemia (Reading et al., 2016). The activity of human G6PD is reduced either due to a decrease in catalytic activity or a reduction in the number of active G6PD molecules (Boonyuen et al., 2016).

Analysis of a bac operon-silenced strain suggests pleiotropic effects of bacilysin in Bacillus subtilis
Ertekin, Ozan; Taskin, Ash Aras; Demir, Mustafa; Karataş, Ayten; Özcengiz, Gülay (Springer Science and Business Media LLC, 2020-04-01)
Bacilysin, as the simplest peptide antibiotic made up of only L-alanine and L-anticapsin, is produced and excreted by Bacillus subtilis under the control of quorum sensing. We analyzed bacilysin-nonproducing strain OGU1 which was obtained by bacA-targeted pMutin T3 insertion into the parental strain genome resulting in a genomic organization (bacA '::lacZ::erm::bacABCDEF) to form an IPTG-inducible bac operon. Although IPTG induction provided 3- to 5-fold increment in the transcription of bac operon genes, n...
RanBPM (RanBP9) regulates mouse c-Kit receptor level and is essential for normal development of bone marrow progenitor cells.
Puverel, S; Kiriş, Erkan; Singh, S; Klarmann, KD; Coppola, V; Keller, JR; Tessarollo, L (Impact Journals, LLC, 2016-12-20)
c-Kit is a tyrosine kinase receptor important for gametogenesis, hematopoiesis, melanogenesis and mast cell biology. Dysregulation of c-Kit function is oncogenic and its expression in the stem cell niche of a number of tissues has underlined its relevance for regenerative medicine and hematopoietic stem cell biology. Yet, very little is known about the mechanisms that control c-Kit protein levels. Here we show that the RanBPM/RanBP9 scaffold protein binds to c-Kit and is necessary for normal c-Kit protein e...
Investigation of the cellular mechanisims underlying the Carboxypeptidase E mutation
Kaşıkçı, Feride; Yanık, Tülin; Department of Biology (2014)
Carboxypeptidase E (CPE) is an enzyme expressed in both endocrine and neuroendocrine cells functioning as both an exopeptidase and a sorting receptor. Recently, it has been reported that CPE plays a role in preventing neuronal cell death in the CA3 hippocampus so as to maintain normal cognitive function in the adult brain. Studies on CPE-knockout mice showed total degeneration of neurons in the CA3 region of the hippocampus in adult mice 4 weeks of age and older. Additionally, increased CPE expression was i...
Obtaining durable enzyme powder via spray drying
Namaldı, Ayşegül; Adalı, Orhan; Department of Chemical Engineering (2005)
Serine alkaline protease (SAP, EC 3.4.21.62) produced by Bacillus species, that are the microbioreactors within the bioreactors, is one of the major industrial enzymes. In this study, after production by Recombinant Bacillus subtilis (BGSC-1A751), carrying pHV1431::subc gene in the complex media and separation of solids, SAP was dried by using a spray drier. Experiments were performed to investigate the stabilization of SAP during spray drying and subsequent storage. Initially, the effect of air inlet tempe...
Investigation of SNX3 in colon cancer
Cingöz, Harun; Erson Bensan, Ayşe Elif; Department of Biology (2019)
Sorting Nexin 3 (SNX3) is part of the retromer complex that recycles cargo receptors back to plasma membrane or to Trans Golgi Network. WNT ligand carrier protein Wntless (WLS) is a known SNX3 cargo protein. Our earlier data suggested over expression of SNX3 in colon cancer cells. Considering its importance in receptor recycling, we hypothesized SNX3 to be a potential modulator of cancer related receptors. To begin understanding the role of SNX3, we developed RNAi models of SNX3 in SW480 colon cancer cells ...
