Enzymes act as essential catalysts in various metabolic reactions. They control the majority of biochemical reactions in cells - from transcription (RNA polymerase) and replication (DNA polymerase) of genetic information to digestion. The majority of enzymes are proteins, although some nucleic acids can also act as enzymes (e.g. snRNA, deoxyribozyme). Our catalog of highly pure enzymes, many of which are produced recombinantly, covers a broad spectrum of metabolic pathways for various research questions.
