Ribozyme in Biological Definition

Enzyme

... Enzyme Catalysis. These works demonstrated the role of conformational transformations in catalytic reactions. Ribozymes An RNA enzyme or " ribozyme " is made of RNA instead of protein. Generally, ribozymes only catalyze RNA splicing , though one notable exception is the RNA portion of the ribos...
