The Crystal Structure of Nitrosomonas europaea Sucrose Synthase Reveals Critical Conformational Changes and Insights into Sucrose Metabolism in Prokaryotes.
UNLABELLED In this paper we report the first crystal structure of a prokaryotic sucrose synthase from the nonphotosynthetic bacterium Nitrosomonas europaea. The obtained structure was in an open form, whereas the only other available structure, from the plant Arabidopsis thaliana, was in a closed conformation. Comparative structural analysis revealed a "hinge-latch" combination, which is critic...
متن کاملCharacterization of the highly efficient sucrose isomerase from Pantoea dispersa UQ68J and cloning of the sucrose isomerase gene.
Sucrose isomerase (SI) genes from Pantoea dispersa UQ68J, Klebsiella planticola UQ14S, and Erwinia rhapontici WAC2928 were cloned and expressed in Escherichia coli. The predicted products of the UQ14S and WAC2928 genes were similar to known SIs. The UQ68J SI differed substantially, and it showed the highest isomaltulose-producing efficiency in E. coli cells. The purified recombinant WAC2928 SI ...
متن کاملCrystal structures of human IPP isomerase: new insights into the catalytic mechanism.
Type I isopentenyl diphosphate (IPP): dimethylally diphosphate (DMAPP) isomerase is an essential enzyme in human isoprenoid biosynthetic pathway. It catalyzes isomerization of the carbon-carbon double bonds in IPP and DMAPP, which are the basic building blocks for the subsequent biosynthesis. We have determined two crystal structures of human IPP isomerase I (hIPPI) under different crystallizat...
متن کاملProcessing OLIGOSACCHARIDES AND THE SUCROSE CRYSTAL HABIT
1 i The sucrose crystal habit has changed over recent years as a result of a substantial variation in the nature of juice impurities. This has had an impact on the quality of sugar and on the performance of the factory. The aim of the work described here was to find I I out how some oligosaccharides, obtained in different ways, affect the sucrose crystal 4 habit. Several experiments were done t...
متن کاملEnergetics of sucrose transport into protoplasts from developing soybean cotyledons.
The accumulation of tetraphenylphosphonium (TPP(+)), 5,5'-dimethyl-oxazolidine-2,4-dione (DMO), and a micro pH electrode were used to measure membrane potential, intracellular and extracellular pH, respectively, upon the addition of exogenous sucrose to soybean cotyledon protoplasts. Addition of sucrose caused a specific and transient (a) depolarization of the membrane potential (measured by TP...
