Background and Aims: Q59L mutant of L-asparaginase enzyme from Escherichia coli (E. coli) has been introduced with lower side effects. This version of the enzyme might have potential applications in the treatment of leukemia patients. We utilized SHuffle T7 strain of E. coli, to produce the mutant enzyme in the presence of chaperone molecules. Materials and Methods: Q59LAsp gene was cloned in...
Abstract: Background: Streptokinase has been widely prescribed as a fibrinolytic agent for myocardial infarction. Simple structural characteristics of this protein have provided techniques for production of different recombinant types of this protein. The present study was designed to prepare equisimilisH46A subtype of streptokinase in our country. Materials and methods: Having extracted the...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
شوری خاک یکی از عوامل مهم محیطی است که منجر به کاهش عملکرد گیاهان زراعی می شود. شناخت مکانیسم های مقاومت گیاهان در برابر تنش ها می تواند به شناسایی ژن های مقاومت و کاربرد آن ها در اصلاح گیاهان و افزایش محدوده کشت گیاهان منجر شود. روش آنالیز expressed sequence tag (est) و داده های ریزآرایه راهی سریع و منطقی برای شناسایی ژن های نامزد جدید برای مقاومت به تنش ها می باشد. در این تحقیق تعداد 2 کتابخا...
Introduction: Immune Protein A is a component with a vast spectrum of biochemical, biological and medical usages. The coding gene of this protein was extracted from Staphylococcus aureus and was cloned and expressed in Escherichia coli bacteria. Suitable statistical methods are utilized to optimize expression conditions for evaluating experiment accuracy , guarantee the accuracy of subsequent ...
Estimation of protein stability is important for many reasons: first providing an understanding of the basic thermodynamics of the process of folding, protein engineering, and protein stability plays important role in biotechnology especially in food and protein drug design. Today, proteins are used in many branches, including industrial processes, pharmaceutical industry, and medical fields. A...
The chemical composition and in vitro gas production of some leguminous browse species were evaluated. Crude protein (CP) content was highest (P
An experiment was carried out to investigate the effects of different levels of energy (2700, 2900 and 3100 kcal/kg) and protein (13, 14.5 and 16 %) on laying performance of Fars native hens during the first phase of production. Two hundred and sixteen 25-week-old native pullets were put into fifty four groups of similar live weight (994 ± 169 gr) of four chickens, which were randomly allocated...

The ability to produce proteins is currently a major biological, physical, and computational challenge in protein research. Given a standard set of conditions, less than 30% of any given genome is expressible in a recombinant host. Protein expression requires complex, lengthy procedures, and specific proteins commonly require individual strategies for optimal expression. Standard bench-level pr...
