Abstract Both AMP and GMP were transphosphorylated rapidly to the corresponding nucleoside-diphosphates and triphosphates by ATP and by other high energy phosphate compounds with cell free extracts of Brevibacterium ammoniagenes. Some enzyme inhibitors, such as metals and PCMB were shown to inhibit the phosphorylations of AMP and GMP. Higher levels of ATP, ADP, GTP and GDP also inhibited the activity of the partially purified ATP-AMP transphosphorylating enzyme (s). In guanine nucleotides fermentation by salvage synthesis with this strain, addition of these inhibitors to the medium increased the amounts of GMP and total guanine nucleotides accumulated. On the contrary, supplement of xylene or of other organic solvents to the medium stimulated the accumulation of bothe GTP and total guanine compouuds in this fermentation. From enzymatic studies, these solvents are presumed to have the ability to change cell permeability. Such findings give an effective method for controlling the amounts of nucleotides accumulated in these fermentations.
