Effect of polyamines on synthesis and degradation of guanosine 5′-diphosphate 3′-diphosphate
Biochimica et Biophysica Acta (BBA) - General Subjects, 1983The effect of polyamines on the in vitro and in vivo synthesis and degradation on guanosine 5'-diphosphate 3'-diphosphate (ppGpp) has been studied in Escherichia coli. The presence of 2 mM spermidine lowered the optimal Mg2+ concentration for ppGpp formation from 17 mM to 11 mM.

In contrast to the reactivity of geranyl methylene-diphosphonate in the reaction catalyzed by farnesyl diphosphate synthase, that of isopentenyl methylenediphosphonate showed an optimum at a more acidic pH than that of isopentenyl diphosphate, and it was inhibited by magnesium ions under certain conditions.

Publisher Summary This chapter describes the method for the preparation of aldose 1,6-diphosphates. A microanalytical procedure is developed to measure the effect of time of incubation and temperature on the rate and extent of the phosphorylation reaction. In this assay, the sugar diphosphate product is partially purified and the rate of formation of
