WebRibonucleases (RNases) constitute a superfamily of nucleases that catalyze the hydrolysis of 3′,5′-phosphodiester linkages in RNA. For the majority of RNases, the catalysis involves the formation of nucleoside 2′,3 ‘-cyclic phosphate intermediates and generation of the products with a 3′-phosphate group. WebOct 2, 2024 · Where does RNase A work? RNase A efficiently catalyzes the cleavage of the P–O5′ bond of RNA specifically after pyrimidine residues (Figure 1). This enzyme has been the object of landmark work on enzymology; on the folding, stability, and chemistry of proteins; and on molecular evolution.
