Salvage synthesis of purine nucleotides by Helicobacter pylori
Journal of Applied Bacteriology, 1994G.L. MENDZ, B.M. JIMENEZ, S.L. HAZELL, A.M. GERO AND W.J. O'SULLIVAN. 1994. The incorporation of purine nucleotide precursors into Helicobacter pylori and the activities of enzymes involved in nucleotide salvage biosynthetic pathways were investigated by radioactive tracer analysis and nuclear magnetic resonance spectroscopy.

Plant Nucleotide Sugar Formation, Interconversion, and Salvage by Sugar Recycling*
Annual Review of Plant Biology, 2011Nucleotide sugars are the universal sugar donors for the formation of polysaccharides, glycoproteins, proteoglycans, glycolipids, and glycosylated secondary metabolites. At least 100 genes encode proteins involved in the formation of nucleotide sugars.

The role of gene duplication in the evolution of purine nucleotide salvage pathways.
Origins of life and evolution of the biosphere : the journal of the International Society for the Study of the Origin of Life, 1998Purine nucleotides are formed de novo by a widespread biochemical route that may be of monophyletic origin, or are synthesized from preformed purine bases and nucleosides through different salvage pathways. Three monophyletic sets of purine salvage enzymes, each of which catalyzes mechanistically similar reactions, can be identified: (a) adenine ...

Interrelation between salvage of purine nucleotides and protein synthesis in rat heart cells
Archives of Biochemistry and Biophysics, 1985The effect of transition from a respiring to a respiration-inhibited state on the rate of protein synthesis was investigated in glycolyzing, cultured rat heart cells. The rate was found to be significantly lower after blocking respiration, and it was further decreased by L-lactate.

Abstract The guinea pig vas deferens has been found to possess at least two active anabolic pathways for adenine nucleotide biosynthesis. Our studies in vitro show that [ 3 H]adenosine and [ 3 H]adenine may be important precursors in purine salvage. Both precursors are eventually converted to [ 3 H]AMP prior to final incorporation into [ 3 H]ATP. [

Adenine salvage enzymes and intracellular nucleotide triphosphate content in Physarum flavicomum amoebae during growth and development [PDF]
Canadian Journal of Microbiology, 1989 The specific activity of adenine phosphoribosyltransferase (APRT) (EC 2.4.2.7) and adenosine phosphorylase (EC 2.4.2.-), two enzymes involved in the utilization of exogenous adenine, was measured in extracts of myxamoebae-swarm cells of Physarum flavicomum undergoing growth, microcyst formation (control), and during adenine inhibition of encystment ...

Biochimica et Biophysica Acta (BBA) - General Subjects, 1985
The pools of free ribose 1-phosphate and deoxyribose 1-phosphate have been measured in Bacillus cereus. It is shown that crude extracts of the same organism can actively utilize the sugar phosphates to convert adenine to ATP and deoxyATP, via a 'salvage' pathway, involving adenine ribosylation (or deoxyribosylation), followed by multiple ...

The effect of undernutrition on the activity of two key enzymes of purine salvage pathway, namely hypoxanthine-guanine phosphoribosyltransferase (HGPRTase) and adenine phosphoribosyltransferase (APRTase), in cerebral hemispheres, cerebellum and brain stem of rats at different days of postnatal development was studied.
