설명

일반 설명

RNase A, Ribonuclease A, is an endoribonuclease that cleaves the phosphodiester bonds of single strand RNA after pyrimidine nucleotides. It attacks at the 3′ phosphate end (For example pG-pG-pC-pA-pG will be cleaved to give pG-pG-pCp and A-pG). The highest activity is exhibited with single stranded RNA. RNase A is a single chain polypeptide containing 4 disulfide bridges. In contrast to RNase B, it is not a glycoprotein. Ribonucleases do not hydrolyze DNA, because the DNA lacks 2′-OH groups essential for the formation of cyclic intermediates. RNase A can also hydrolyze RNA from protein samples. RNase A can be inhibited by alkylation of His12 and His119 and activated by potassium and sodium salts. RNAse is inhibited in the presence of heavy metal ions. RNase is also inhibited competitively by DNA.

애플리케이션

• RNase A is used to remove RNA from DNA plasmid and genomic DNA preparations and protein samples.
• RNase A is also used in RNA sequence analysis and protection assays.
• RNase A has been used as a tool for computer-aided drug design.
• RNase A supports the analysis of RNA sequences.
• RNase A hydrolyze RNA contained in protein samples.
• Purification of DNA is supported by RNase A.

생화학적/생리학적 작용

Ribonuclease A is an endoribonuclease that cleaves single stranded RNA after pyrimidine nucleotides. It attacks at the 3′ phosphate end. Ribonucleases do not hydrolyze DNA, because the DNA lacks 2′-OH groups essential for the formation of cyclic intermediates. RNase can also hydrolyze RNA from protein samples. RNase A can be inhibited by alkylation of His¹² and His¹¹⁹ and activated by potassium and sodium salts.
