Unified prebiotically plausible synthesis of pyrimidine and purine RNA ribonucleotides
Science, 2019 Conditions right for making nucleosides In the absence of biological catalysts and metabolism, can atmospheric and geochemical processes provide the substrates and conditions required for production of biological molecules? Becker et al.

Human de novo purine biosynthesis
Critical reviews in biochemistry and molecular biology, 2020 The focus of this review is the human de novo purine biosynthetic pathway. The pathway enzymes are enumerated, as well as the reactions they catalyze and their physical properties. Early literature evidence suggested that they might assemble into a multi-

Purine and purinergic receptors
Brain and Neuroscience Advances, 2018 Adenosine 5′-triphosphate acts as an extracellular signalling molecule (purinergic signalling), as well as an intracellular energy source. Adenosine 5′-triphosphate receptors have been cloned and characterised. P1 receptors are selective for adenosine, a

Basis for the control of purine biosynthesis by purine ribonucleotides. [PDF]
Journal of Clinical Investigation, 1981 An animal model was used to determine the basis for the increase in purine biosynthesis that results from hepatic depletion of purine nucleotides, such as seen in patients with type I glycogen storage disease or following fructose administration. Mice were injected intravenously with glucose or fructose, 2.5 mg/g of body weight, and the animals were ...
