Proteinase K

Proteinase K from Tritirachium album expressed recombinantly  in Pichia pastoris

Proteinase K is a subtilisin-like serine protease with a broad substrate specificity. The enzyme degrades both terminal (exopeptidase activity) and internal (endopeptidase activity) peptide bonds.
It is widely used for digestion of proteins, including DNases and RNases during nucleic acid preparations without compromising the integrity of the isolated DNA or RNA.
During production of the recombinant enzyme almost all nucleic acids are removed. Therefore, it is especially suitable for PCR reactions.

Inactivation and degradation of nucleases during isolation of nucleic acids from tissues, pro- or eukaryotic cells.
