Proteinase K In DNA/RNA Extraction

Proteinase K In DNA/RNA Extraction

Protease K is a serine protease with efficient enzymatic activity and broad substrate specificity, preferentially breaking down ester and peptide bonds adjacent to the C-terminus of hydrophobic, sulfur-containing, and aromatic amino acids, and is often used to degrade proteins to produce short peptides. It has the typical catalytic triad Asp39-His69-Ser224 characteristic of serine proteases and has two Ca2+ binding sites around the active center to increase its stability, allowing it to maintain high enzymatic activity under a wider range of conditions.
