title: ClpP: a distinctive family of cylindrical energy-dependent serine proteases.
abstract: Processes maintaining protein homeostasis in the cell are governed by the activities of molecular chaperones that mainly assist in the folding of polypeptide chains and by a large class of proteases that regulate protein levels through degradation. ClpP proteases define a distinctive family of cylindrical, energy-dependent serine proteases that are highly conserved throughout bacteria and eukaryota. They typically interact with ATP-dependent AAA+ chaperones that bind and unfold target substrates and then translocate them into ClpP for degradation. Structural and functional studies have provided a detailed view of the mechanism of function of this class of proteases.
