accurate protein function prediction is an important subject in bioinformatics, especially wheresequentially and structurally similar proteins have different functions. malate dehydrogenaseand l-lactate dehydrogenase are two evolutionary related enzymes, which exist in a widevariety of organisms. these enzymes are sequentially and structurally similar and sharecommon active site residues, spati...
ammonia is the chief excretory product in fishes. however, non-availability of enough of water in the habitat, may lead to the formation of urea, in fishes. in the present study, the possible role of urea formation to avoid the toxicity of ammonia under water-restricted condition was tested in channa gachua. circulatory urea and ammonia were estimated in the blood of the fishes and glutamate de...
An electrochemically assisted “block and unblock” procedure is employed to immobilise three enzymes (alcohol dehydrogenase, formaldehyde dehydrogenase formate dehydrogenase) sequentially independently at individual gold electrodes.
cellobiose dehydrogenase (cdh ec.1.1.5.1) is an extracellular enzyme that mainly produced by wood-degrading fungi. it oxidizes cellobiose to cellobionolactone using a wide spectrum of electron acceptors. the key roles of cdh in growth, metabolism, and some other important cellular processes such as cellulose degradation in fungi have been noted. since the demands for finding new sources of cdh ...
infertility can be caused by an unexplained reduction in semen quality in males who present asnormal on physical examination and endocrine testing. there is some evidence that aberrantmetabolism of micronutrients such as choline may play a causative role in male factorinfertility. choline is a crucial factor in the regulation of sperm membrane structure andmotility, and this nutrient plays an i...
amino acid dehydrogenases (l-amino acid: oxidoreductase deaminating ec 1.4.1.x) are members of the wider superfamily of oxidoreductases that catalyze the reversible oxidative deamination of an amino acid to its keto acid and ammonia with the concomitant reduction of either nad+, nadp+ or fad. these enzymes have been received much attention as biocatalysts for use in biosensors or diagnostic kit...
some kinetic properties of nad+- and nadp+- dependent glucose 6-phosphatedehydrogenase (g6pd) purified from streptomyces aureofaciens were studied. both nadh andnadph inhibited the enzyme competitively and noncompetitively, with respect to the correspondingcoenzymes and glucose 6-phosphate, respectively. atp inhibited the nad+ - linked reaction but not thatof the nadp+- linked activity. the inh...
جو (hordeum vulgare l.) یکی از قدیمی ترین گیاهان زراعی است که از نظر تولید جهانی، چهارمین غله بعد از گندم، برنج و ذرت محسوب می شود. دامنه وسیع سازگاری جو، موجب زراعت آن در مناطقی شده که تولید سایر غلات، مانند ذرت، برنج و حتی گندم امکان پذیر نمی-باشد. تنش های محیطی از قبیل خشکی، شوری و سرما نقش مهمی بر عملکرد گیاهان زراعی و بقای آن ها دارند. دمای پایین یکی از عوامل محیطی است که توزیع گیاهان، زند...
the present study was aimed to evaluate the therapeutic potential of pimpinella tirupatiensis (pt) by assaying the activities of selective mitochondrial enzymes in streptozotocin induced diabetic rats. diabetic rats showed a significant (p < 0.01) reduction in the activities of oxidative enzymes succinate dehydrogenase (sdh), malate dehydrogenase (mdh), glutamate dehydrogenase (gdh) and isocitr...
background: this study was conducted to determine of molecular epidemiology of the giardia lamblia by pcr-rflp method in tehran, capital of iran. methods: thirty eight stool samples were randomly selected from 125 patients diagnosed with giardiasis using microscopy in tehran. dna extraction of some samples were performed by phenol/chloroform/isoamyl alcohol method and to raise the sensitivity ...
