Abstract:
Regulated intramembrane proteolysis (RIP) is a widely distributed mechanism of signal transduction in which membrane-bound proteases cleave transmembrane domains of substrate proteins. The site-2 protease (S2P) class of RIP metalloproteases is present in most bacterial genomes but is generally of unknown function except for the well-characterized proteases RseP and SpoIVFB. In this review we will discuss the biochemical functions and physiologic roles of S2P proteases in bacteria and highlight recent data implicating S2P family members in host-pathogen interactions.

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 (ubiquitin...
