Endoproteases

Endoprotease Lys/Arg-Arg (Kex)

Features

• specific serine endoproteinase
• cleaves amino acid sequence N-Arg-Arg/-C and N-Lys-Arg/-C at the carboxyl end
• suited for protein sequencing and cleavage of fusion proteins with an appropriate recognition sequence

Product Description

In the series of endoproteinases we also offer the newly developed endoproteinase Lys/Arg-Arg. The specific serine endoproteinase (universal serine-protease) has a MW of 68 kDa. It cleaves at the carboxyl end of the recognition sequences: Arg-Arg/X and Lys-Arg/X and thus provides new possibilities for e.g. the development of fusion protein systems with alternative cleavage sites.
