Abstract
The incorporation of proteins (eg CaneCPI-5) into the acquired pellicle (AP) has favored its ability to protect against erosion. In this context, a new cysteine protease inhibitor protein (cystatin) derived from Maqui Berry (MaquiCPI-3) deserves to be studied, due to some characteristics similar to CaneCPI-5 and its high yield when heterologously expressed in bacteria. Initial in vitro re…
