Construction of New Genetic Tools as Alternatives for Protein Overexpression in Escherichia coli and Pseudomonas aeruginosa
Background: Pseudomonas protein expression in E. coli is known to be a setback due to signifi cant genetic variation and absence of several genetic elements in E. coli for regulation and activation of Pseudomonas proteins. Modifi cations in promoter/repressor system and shuttle plasmid maintenance have made the expression of stable and active Pseudomonas protein possible in bot...
متن کاملOxa1p, an essential component of the N-tail protein export machinery in mitochondria.
A number of nuclear encoded inner membrane proteins of mitochondria span the membrane in such a manner that their N termini are located in the intermembrane space. Many of these proteins attain this membrane orientation by undergoing an export step from the matrix across the inner membrane. This export process, which resembles bacterial N-tail export from energetic and topogenic signal requirem...
متن کاملa swot analysis of the english program of a bilingual school in iran
با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...
15 صفحه اولProtein export in Escherichia coli requires a soluble activity.
By using a reconstituted cell-free system we have demonstrated the existence of a soluble activity that is required for the export of proteins in Escherichia coli. This export factor sediments at about 12 S. It has been partially purified by passage through an omega-NH2-butylagarose column and by salt elution off a DEAE matrix. The export factor does not contain 6S RNA.
