Boc-Leu-Arg-Arg-AMC (Boc-LRR-AMC)

Catalog #: S-300

Product Source:

Synthetic

Fluorogenic tri-peptide substrate for measuring the "trypsin-like" peptidase activity of the 20S proteasome. Each of the two 20S internal β-type rings harbors three different proteolytically active sites: β1 ("post-glutamyl peptide hydrolase" site), β2 ("trypsin-like" site) and β5 ("chymotrypsin-like" site). This peptide is also substrate for the Kex2 endopeptidase from S. Cervisiae, which has substrate specificity toward the C-terminal side of LR, PR and RR sequences. In addition, the peptide can be cleaved by Kalikrein 5 with a P1 site preference for basic residues (R and K).
