A synthesis of 11-phenoxyundecyl phosphate and its biochemical transformation (using GlcNAc-P transferase from Salmonella arizonae O:59 membranes catalysing transfer of GlcNc-phosphate from UDP-GlcNAc on lipid-phosphate) into P1-11-phenoxyundecyl, P2-2-acetamido-2-deoxy-α-d-glucopyranosyl diphosphate are described. 相似文献

A new scheme of synthesis of 11-phenoxyundecyl phosphate from 11-bromoundecanoic acid was suggested; its ability to serve as an acceptor of 2-acetamido-2-deoxy-α-D-glucopyranosyl phosphate in a reaction catalyzed by UDP-N-acetylglucosamine: polyprenyl phosphate N-acetylglucosamine phosphotransferase from Salmonella arizona O:59 was demonstrated. 相似文献

The Effect of Local Cooling of Cucumber and Wheat Seedlings on Various Kinds of Stress Resistance of Their Leaves and Roots 总被引:1,自引:0,他引:1
Shoots and roots of wheat (Triticum aestivum L., cold-resistant species) and cucumber (Cucumis sativus L., cold-sensitive species) were chilled at 2°C or 10°C, respectively, for 7 h. The changes in cold, heat, and salt resistance in treated leaf and root cells were recorded. Local cooling of the leaf resulted in an increase of its cold and salt tolerance, but its heat tolerance remained unchanged. At the same time, cold tolerance of the root slightly increased as a result of local cooling, but its heat and salt tolerance decreased. Cooling of the shoot did not affect the cold and heat tolerance of root cells but caused a decrease in their salt tolerance. Finally, in the leaf maintained at a normal temperature, there was an increase in all kinds of stress resistance as a result of root cooling. We discuss the possibility of an unspecific change in stress resistance caused by metabolic shifts. These shifts are induced by a signal, which is transmitted inside the plant into plant organs located at a considerable distance from the chilled ones. 相似文献

Experiments using cucumber (Cucumis sativusL.), wheat (Triticum aestivumL.), and barley (Hordeum vulgareL.) seedlings showed that actinomycin D partially inhibited an increase in the heat-tolerance of leaves heated at 38°C for 7 h but did not affect this index when the roots were heated. Exogenous ABA increased heat-tolerance in both cases. These results, with regard to the data demonstrating an important contribution of protein synthesis to the specific increase in heat-tolerance during the heat acclimation of intact plants, make it possible to conclude that the development of leaf heat-tolerance resulting from the local heating of shoots depends on the induced synthesis of mRNAs and respective proteins. At the same time, there is little or no such dependence during root heating. ABA manifested itself as a factor of a general, nonspecific increase in heat-tolerance during the local heating of both shoots and roots. 相似文献

Undecyl phosphate derivatives with new fluorescent labels, 11-[(2-pyridyl)amino]undecyl phosphate and 11-[(9-anthracenylcarbonyl)amino]undecyl phosphate, were synthesized. These compounds were shown to be acceptor substrates of the galactosyl phosphate residue in the enzymatic reaction catalyzed by galactosyl phosphotransferase from Salmonella anatum or Salmonella newport membrane preparations. 相似文献
