To our knowledge, this is the first work on the influence of species upon the bioactive molecules, antioxidant properties, and enzyme inhibitory capacities against tyrosinase and alpha-amylase ofOnosma polyanthaandO. mollis. The levels of phenolic compounds were from 6.55 to 10.37 mg gallic acid equivalent/g extract. The concentrations of total flavonoids varied from 2.71 to 10.78 mg quercetin equivalent/g extract. Twenty-five compounds were quantified via liquid chromatography - electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS). Significant differences were found between the two species. Chlorogenic acid, rosmarinic acid, hesperidin, and luteolin 7-glucoside were the major compounds in both species. Four antioxidant assays together with two enzyme tests confirmed thatO. polyanthaandO. mollisextracts exhibited remarkable antioxidant and enzyme inhibitory capacities. Statistical analyses confirmed that the biological activities depend on the synergism between phenolic compounds and radicals. The results proposedO. polyanthaandO. mollisspecies as potential sources of bioactive compounds for industrial application.

AMINO-ACID SUBSTITUTIONS WITHIN THE ANALOGOUS NUCLEOTIDE-BINDING LOOP (P-LOOP) OF AMINOGLYCOSIDE 3'-PHOSPHOTRANSFERASE-II KOCABIVIK, S; PERLIN, MH (Elsevier BV, 1994-01-01) 1. Oligonucleotide-directed mutagenesis of APH(3')-II was used to investigate the functions of key amino acids in the P-loop analogous motif of the enzyme. 2. The mutations of Gly205 --> GIu, Gly210 --> Ala and Arg211 --> Pro considerably reduced the resistance of the resulting strains to KM and to related drugs, e.g. G418. 3. Similarly, enzyme activity in the crude extracts of these mutants was substantially reduced as well as the enzyme's affinity for Mg2+ ATP. 4. Alternatively substitutions at a highly c...
Isolation and immunological characterization of theta class glutathione-s-transferase gstt2-2 from bovine liver İşgör, Sultan Belgin; Çoruh, Nursen; Department of Biochemistry (2004) The glutathione-S-transferases (GSTs) (EC.2.5.1.18) are enzymes that participate in cellular detoxification of endogenous as well as foreign electrophilic compounds, function in the cellular detoxification systems and are evolved to protect cells against reactive oxygen metabolites by conjugating the reactive molecules to the nucleophile scavenging tripeptide glutathione (GSH, ?-glu-cys-gly). The GSTs are found in all eukaryotes and prokaryotic systems, in the cytoplasm, on the microsomes, and in the mitoch...
Aromatic amino acid synthesis performance of bacillus acidocaldarius Kocabaş, Pınar; Çalık, Pınar; Department of Chemical Engineering (2004) In this study, the effects of bioprocess operation parameters on aromatic amino acid synthesis performance of Bacillus acidocaldarius were investigated. Firstly, in laboratory scale shake-bioreactors, a defined medium was designed in terms of its carbon and nitrogen sources, to achieve the highest cell concentration. Thereafter, the effects of bioprocess operation parameters, i.e., pH and temperature were investigated; and the optimum medium contained (kg m-3): fructose, 8; (NH4)2HPO4, 5; CaCl2, 0.2; KH2PO4...
Hplc-dad isolation of antioxidant compounds in aesculus hippocastanum bark extracts and cytotoxic effects on hl-60 cells Özdoğan, Nizamettin; Özdoğan, Nizamettin; Department of Biochemistry (2007) This study was designed to investigate the cytotoxic and antioxidative properties of Aesculus hippocastanum L. (A. hippocastanum) bark extracts. Dried and powdered barks were extracted in ethanol, methanol, water and ethylacetate at a ratio of 1:6 (w/v). Antioxidative capacity of each extract (ethanol, methanol, water and ethylacetate) were determined by their ability to scavenge 1, 1 -diphenyl-2-picryl-hydrazyl radical (DPPH). Effective concentration (EC50) values were calculated as 0.010 mg/mL 0.011 mg/mL...
Alteration of enzyme activities and kinetic properties of GST and NQO1 with naturally occurring phenolic compounds KARAKURT, SERDAR; Sever, Melike; Celebioglu, Hasan Ufuk; Adalı, Orhan (Walter de Gruyter GmbH, 2015-01-01) Objective: Glutathione S-transferase (GST) and NAD(P)H:quinine oxidoreductase 1 (NQO1) are the enzymes important in cytoprotection and bioactivation of chemicals. This study has addressed effects of polyphenolic compounds; ellagic acid, quercetin, naringenin, resveratrol, rutin and hesperidin on rabbit liver GST and NQO1 enzyme activities.
