Function

Ribonuclease (RNase) degrades RNA. The endonucleases cleave single or double stranded RNA. Exo-RNases remove terminal nucleotide from the ends of the RNA molecule.

RNase A or RNase I endonuclease which cleaves C or U of single-stranded RNA (ssRNA)^[1]. For details see RNase A, RNase A Oligomers, Ribonuclease A Catalysis, RNaseA Nobel Prizes, User:R. Jeremy Johnson/RNaseA and RNase A NMR.

Active Site of Ribonuclease A

Ribonuclease A cleaves RNA strands by catalyzing a transphosphorylation reaction where the 2'-OH of the ribose sugar attacks the neighboring phosphate, releasing the ribose on the the other side of the phosphate. This structure shows ribonuclease A (in blue) bound to short DNA strand composed of four thymidines (in pink). Ribonuclease binds tightly to DNA, but since DNA is missing the 2'-OH, ribonuclease does not cleave it. are shown that are important for catalysis. The 3' carbon on the DNA is shown in red--it is the site where the 2'-OH is connected in RNA. The two histidines perform the proton transfers that are needed in the reaction, and the lysine stabilizes the intermediate that is formed as the 2'-OH attacks the phosphate. Ribonuclease cleaves RNA strands best next to cytidine and uridine nucleotides--the reason for this may be seen in a . Notice that the small pyrimidine base is surrounded by protein atoms. A larger purine base would not fit well in this space.^[36]
