Abstract:
In cells, proteins are synthesized, function, and degraded (dead). Protein synthesis (spring) is important for the life of proteins. However, how proteins die is equally important for organisms. Proteases are secreted from cells and used as nutrients to break down external proteins. Proteases degrade unwanted and harmful cellular proteins. In eukaryotes, a large enzyme complex called the proteasome is primarily responsible for cellular protein degradation. Prokaryotes, such as bacteria, have similar protein degradation systems. In this review, we describe the structure and function of the ClpXP complex in the degradation system, which is an ATP-dependent protease in bacterial cells, with a particular focus on ClpP.

The Proteasome
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...
