?
CNBr-fragments of bovine serum albumin + H2O
?
-
less dependent on ATP hydrolysis
-
-
?
CspD + H2O
?
-
CspD is a replication inhibitor, which is induced in stationary phase or upon carbon starvation and increases the production of persister cells. CspD is subject to proteolysis by the Lon protease both in vivo and in vitro. Turnover of CspD by Lon is strictly adjusted to the growth rate and growth phase of Escherichia coli, reflecting the necessity to control CspD levels according to the physiological conditions. Truncation or point mutation of CspD does not elevate protein stability

DNA-binding protein HUbeta + H2O
?
-
Lon binds to both histone-like proteins HUalpha and HUbeta, but selectively degrades only HUbeta in the presence of ATP. Preferred cleavage site is the A20-A21, followed in preference by L36-K37. Degradation of substrate mutants A20D and A20Q is more slowly. Mechanism follows at least three stages: binding of Lon with the HU protein, hydrolysis of ATP by Lon to provide energy to loosen the binding to the HU protein and to allow an induced-fit conformational change, and specific cleavage of only HUbeta

UCH-L1-ssrA + H2O
?
ssrA-fusion protein, UCH-L1 is a 52-knotted protein, high activity. In degradation of UCH-L1-ssrA, the degron is located at the C-terminus of the knotted protein. C-terminally tagged UCH-L1-ssrA is not noticeably degraded by ClpXP, while N-terminally tagged ssrA-x-UCH-L1 is degraded by ClpXP. The fact that the C-terminal ssrA-tag is attached directly to beta-strand 6, which is located at the centre of the core beta-sheet structure, may explain the resistance of UCH-L1-ssrA to ClpXP-induced degradation. Mutant UCH-L1-ssrA F162A is stabilised by the mutation, mutant UCH-L1-ssrA F165A is very destabilised

LasI + H2O
?
Lon is involved in the regulation of quorum-sensing signaling systems in Pseudomonas aeruginosa, the opportunistic human pathogen. The enzyme is part of the acyl-homoserine lactone-mediated QS system LasR/LasI, but LasR/LasI regulation is independent of the RhlR/RhlI system by Lon. QS systems are organized hierarchically: the RhlR/RhlI system is subordinate to LasR/LasI, Lon represses the expression of LasR/LasI by degrading LasI, an HSL synthase, leading to negative regulation of the RhlR/RhlI system, overview

protease Lon recognizes specific sequences rich in aromatic residues that are accessible in unfolded polypeptides but hidden in most native structures. Denatured polypeptides lacking such sequences are poor substrates. Lon also unfolds and degrades stably folded proteins with accessible recognition tags.
