Enantioselectivity of human AMP, dTMP and UMP-CMP kinases
L-nucleoside analogues such as lamivudine are active for treating viral infections. Like D-nucleosides, the biological activity of the L-enantiomers requires their stepwise phosphorylation by cellular or viral kinases to give the triphosphate. The enantioselectivity of NMP kinases has not been thoroughly studied, unlike that of deoxyribonucleoside kinases. We have therefore investigated the cap...
متن کاملPotentiation of gustatory response to monosodium glutamate in rat chorda tympani fibers by addition of 5'-ribonucleotides.
5'-Ribonucleotides such as sodium 5'-inosinate (5'-IMP) , sodium 5'-guanylate (5'-GMP) and sodium 5'-xanthylate possess strong flavor-enhancing ability for humans when they are added in a minute quantity to monosodium glutamate (MSG), but little enhancement of taste occur by the addition of sodium 5'-uridylate (5'-UMP) and 5'-cytidylate (5'-CMP) to MSG5). ADACHI1) showed enhancement of the resp...
متن کاملCyclic CMP and cyclic UMP: new (old) second messengers
Historical background As early as 1965 it was proposed that in addition to the well-established second messengers, cyclic AMP and cyclic GMP, the cyclic pyrimidine nucleotides, cyclic CMP (cCMP) and cyclic UMP (cUMP) could play a role as second messenger molecules. This hypothesis was based on the identification of cCMPand cUMP-hydrolyzing phosphodiesterase (PDE) activities in mammalian tissues...
متن کاملSyntheses of some fluorescent ribonucleotides.
Synthesis of guanosine 3'-phosphodiesters of 1, N6-ethenoadenosine-2-sulfonate or 1, N6-etheno-2-azaadenosine can be done readily with ribonuclease N1. There is a 10-fold difference in quantum yield between the phosphodiesters and the starting fluorescent nucleosides. This difference provides the basis for the development of a fluorescent assay for nuclease.
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
