What is the relative ease of RNA hydrolysis?
- The relative ease of RNA hydrolysis is an effect of the presence of the 2' hydroxyl group . A phosphodiesterase is an enzyme that catalyzes the hydrolysis of phosphodiester bonds, for instance a bond in a molecule of cyclic AMP or cyclic GMP . An enzyme that plays an important role in the repair of oxidative DNA damage is the 3'-phosphodiesterase.
What is the rate of hydrolysis?
- The rate of hydrolysis depends on the concentration of silane, the pH of the solution (pH > 10 and pH < 5 give a high rate, pH near 7 gives the slowest rate), and the character of the functional groups of silanes and alkoxy groups [ 20 – 22 ]. Hydrolysis is catalyzed by hydronium ions H 3 O +, hydroxyl ions OH ?, Lewis bases, and some metals.
Why is RNA not susceptible to base-catalyzed hydrolysis?
- RNA is susceptible to this base-catalyzed hydrolysis because the ribose sugar in RNA has a hydroxyl group at the 2’ position. This feature makes RNA chemically unstable compared to DNA, which does not have this 2’ -OH group and thus is not susceptible to base-catalyzed hydrolysis. Mechanism of base catalyzed RNA hydrolysis.
Where does RNA hydrolyze in an alkaline environment?
- The hydrolysis occurs at the phosphodiester bond of the backbone. Hence, RNA rapidly hydrolyzes in an alkaline environment into cyclic 2',3'-monophosphate nucleotides, which undergo further hydrolysis in water to form a mixture of 2'- and 3'-nucleoside monophosphates. This breaking of the backbone of RNA is known as a strand break.
