The products of NTP-catalyzed reactions are typically the corresponding nucleoside diphosphates (NDPs) or nucleoside monophosphates (NMPs), so most cofactor regeneration research has focused on the conversion of these products back to their respective NTPs. Earlier proposals have suggested that the transition state with ADP and Pi bound is the work step used to communicate the hydrolysis energy to electron transfer (31). http://pubs.acs.org/page/copyright/permissions.html. Both hydrolyses were found to proceed via different mechanisms; the acidic system reacted by means of concerted general acid catalysis (found to be a so-called DNANAHDxh mechanism), whereas the neutral system reacted by way of a different mechanism (namely, DN*ANDxhAH). dGTP) were synthesized.The lability of the formamide group required that nucleoside triphosphate formation be carried out using an umpolung strategy in which pyrophosphate was activated toward nucleophilic … Nucleoside triphosphate pyrophosphohydrolase activity of MazG.
