synthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
15 صفحه اولCharacterization of osmotin : a thaumatin-like protein associated with osmotic adaptation in plant cells.
Cultured tobacco (Nicotiana tabacum var Wisconsin 38) cells adapted to grow under osmotic stress synthesize and accumulate a 26 kilodalton protein (osmotin) which can constitute as much as 12% of total cellular protein. In cells adapted to NaCl, osmotin occurs in two forms: an aqueous soluble form (osmotin-I) and a detergent soluble form (osmotin II) in the approximate ratio of 2:3. Osmotin-I h...
متن کاملRegulation of the Osmotin Gene Promoter.
By introducing a chimeric gene fusion of the osmotin promoter and [beta]-glucuronidase into tobacco by Agrobacterium-mediated transformation, we have demonstrated a very specific pattern of temporal and spatial regulation of the osmotin promoter during normal plant development and after adaptation to NaCl. We have found that the osmotin promoter has a very high natural level of activity in matu...
متن کاملOsmotin gene expression is posttranscriptionally regulated.
Accumulation of both osmotin mRNA and osmotin protein in tissues of tobacco (Nicotiana tabacum L. var Wisconsin 38) is subject to complex developmental control. Osmotin was found to be most abundant in tobacco roots and in tissues of the outer stem comprised primarily of epidermis, and it was less abundant in the corolla. It was a minor protein in other tissues and was undetectable in some tiss...
متن کاملDissecting the regulation of yeast genes by the osmotin receptor.
The Izh2p protein from Saccharomyces cerevisiae is a receptor for the plant antifungal protein, osmotin. Since Izh2p is conserved in fungi, understanding its biochemical function could inspire novel strategies for the prevention of fungal growth. However, it has been difficult to determine the exact role of Izh2p because it has pleiotropic effects on cellular biochemistry. Herein, we demonstrat...
