Does RNA hydrolysis involve rate-limiting formation of the pentacoordinate intermediate or rate-limiting decomposition? Phenyl ester of adenosine 3'-phosphate as a novel probe.
The rate-limiting step of enzymatic and non-enzymatic hydrolysis of RNA has been experimentally determined by use of phenyl ester of adenosine 3'-phosphate as a novel probe. Alkaline hydrolysis of RNA involves rate-limiting decomposition of a pentacoordinate intermediate, and any catalyst, either enzymatic or non-enzymatic, should promote the decomposition step.
