Question: rnase is an enzyme that cleaves the p-o?
Answer: RNAse is an enzyme that cleaves the P-O^5 bond in RNA. ... The RNAse reaction is an example of metal ion catalysis with a positively charged metal. Both His residues are deprotonated at pH higher than 6.5. The substrate is affected by the change in pH, and is inactive (+ charged) when pH is above -6.0.
