RNAse is an enzyme that cleaves the P--O^5' bond in RNA. it has two His residues in the active site. Suggest a plausible explanation why the enzyme activity changes when pH is increased or decreased from ~pH 6.0,
Choose all the true statements
a.) the RNAse reaction is an example of metal ion catalysis with a positively charged metalb.) both His residues are deprotonated at pH higher than 6.5c.) one His residue abstracts a proton from the substrate at pH 6.0, whereas the other denotes a protond.) there are two His residues, and both are deprotonated below pH 4.2e.) the substrate is affected by the change in pH, and is inactive (+ charged) when pH is above ~6.0
