Description
The fluorogenic substrate Boc-RVRR-AMC is efficiently cleaved by furin, a mammalian homolog of the yeast Kex2 endoprotease (kcat/Km approx. 4·10³ M⁻¹s⁻¹). As a calcium-dependent serine protease associated with Golgi membranes, furin is responsible for the secretory processing of precursor proteins at paired basic residues. Boc-RVRR-AMC is also cleaved by proprotein convertase 4. Stock solutions of Boc-RVRR-AMC are best prepared in DMSO.
