What are the differences between proteinase K and protease?
Posted May 19, 2023
Proteinase K is a broad-spectrum serine protease enzyme that acts mainly on keratin protein. It plays a key role in digestion of proteins and eliminating contamination from nucleic acid preparations.
Protease is an enzyme catalyzing proteolysis. It acts mainly on the proteins in foods and plays a key role in multiple biological functions including cell signaling, digestion of ingested proteins, and protein catabolism.
