RNA metabolism enzyme

The term RNA metabolism enzyme refers to any enzyme participating in the processing, modification, maturation, or turnover of RNA molecules within the cell[2][8][9]. These enzymes include canonical ribonucleases (e.g., RNase A, RNase E, RNase III), tRNA processing enzymes (RNase T, RNase PH, RNase Z), polymerases, helicases, and ligases. They function in reactions such as RNA cleavage, splicing, polyadenylation, nucleotide addition, and unfolding of RNA structures. Their activity is crucial for gene expression, cell growth, and response to stress. RNA metabolism enzymes have important roles in disease, as improper RNA processing can cause cancer, neurodegeneration, and infection. The "RNA metabolism enzymes" term is too broad for single therapeutic target designation: individual enzymes within this class are the actual drug targets, diagnostic markers, or research tools, rather than the whole class. Each specific enzyme may belong to a unique molecular family or subclass (e.g., RNase A superfamily, RNA polymerases, etc.), have distinct mechanisms, and interact with different inhibitors or drugs.
