Borate-guided ribose phosphorylation for prebiotic nucleotide

WebbRibose-5-phosphate isomerases (EC 5.3.1.6) inter-convert ribose-5-phosphate and ribulose-5-phosphate. This reaction allows the synthesis of ribose from other sugars, as well a means for salvage of carbohydrates after nucleotide breakdown. Two unrelated types of enzyme are known to catalyze the isomerization. The most common one, RpiA, … WebbThe final preparation was essentially free of purine base, unhydrolyzed nucleotide, and inorganic phosphate, and contained in some cases a small amount of BaC03. The ease of obtaining ribose-5-phosphate by this method from the readily available nucleotide, ATP, should make the use of these highly purified preparations more practical.
