Katepsin K (EC 3.4.22.38, katepsin O2) je enzim.[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju
- Široka proteolitička aktivnost na malim molekulima. Glavna odrednica specifičnosti je P2, koji je preferentno Leu, Met > Phe, i odsustvo Arg
Ovaj enzim je prominentno izražen u osteoklastima sisara.
