Boc-QRR-pNA (Boc-Gln-Arg-Arg-pNA) is commonly used in biochemical research as a substrate for Kex2 protease. This substrate exhibits no absorbance at 405 nm. Upon cleavage by Kex2 protease at the RR site, it yields two fragments: Boc-Gln-Arg-Arg and pNA. The released pNA shows absorbance at 405 nm, and the absorbance intensity is directly proportional to its concentration.
