What is the role of pyrophosphatase in RNA polymerization?

In chemistry, pyrophosphates are phosphorus oxyanions that contain two phosphorus atoms in a P–O–P linkage. A number of pyrophosphate salts exist, such as disodium pyrophosphate (Na2H2P2O7) and tetrasodium pyrophosphate (Na4P2O7), among others. Often pyrophosphates are called diphosphates. The … Meer weergeven Pyrophosphoric acid is a tetraprotic acid, with four distinct pKa's: H4P2O7 ⇌ [H3P2O7] + H , pKa = 0.85 [H3P2O7] ⇌ [H2P2O7] + H , pKa = 1.96 [H2P2O7] ⇌ [HP2O7] + H , pKa = 6.60 [HP2O7] ⇌ … Meer weergeven The anion P 2O 7 is abbreviated PPi, standing for inorganic pyrophosphate.
