Chymotrypsin-like activity of beta 5 (β5) subunit (Leishmania donovani) (β5 subunit)

Target
β5 subunit
Molecular classification
Enzyme, Protease, Proteasome subunit
01

Overview

The chymotrypsin-like activity of the β5 subunit is a proteolytic function within the 20S proteasome complex of *Leishmania donovani*. It is essential for regulated protein degradation, maintaining cellular homeostasis by removing damaged or unneeded proteins. Inhibition of this activity is a validated drug target.
