Mitochondria are multifunctional organelles that play a central role in energy metabolism. Owing to the life-essential functions of these organelles, mitochondrial content, quality and dynamics are tightly controlled. Across the species, highly conserved ATP-dependent proteases prevent malfunction of mitochondria through versatile activities. This study focuses on a molecular function of the plant mitochondrial inner membrane-embedded AAA protease (denoted i-AAA) FTSH4, providing its first bona fide substrate. Here, we report that the abundance of the Tim17-2 protein, an essential component of the TIM17:23 translocase (Tim17-2 together with Tim50 and Tim23), is directly controlled by the proteolytic activity of FTSH4. Plants that are lacking functional FTSH4 protease are characterized by significantly enhanced capacity of preprotein import through the TIM17:23-dependent pathway. Taken together, with the observation that FTSH4 prevents accumulation of Tim17-2, our data point towards the role of ...

Introduction - ATP-dependent proteases constitute a unique proteolytic system. Although proteolysis is an exergonic process, these proteases require energy derived from ATP hydrolysis in order to function. This energy requirement is closely related to their structures and mechanisms of action. Their proteolytic active sites are usually sequestered in barrel-like structures that prevent uncontrolled proteolysis. These ring shaped proteolytic domains, or proteolytic sub-complexes, are connected to and cooperate with structurally similar ATPase domains or ATPase sub-complexes. Substrates bind to these ATPase domains or ATPase sub-complexes and the energy released by ATP hydrolysis is used to unfold and translocate the substrate into the proteolytic cavity and to activate the proteases themselves. ATP-dependent proteases are present in all prokaryotic and eukaryotic cells. In eukaryotic cells, they are localized in the cytosol and in the nucleus (proteasome) as well as in the organelles: ...
Strikingly, inactivation or loss of the m-AAA protease does not result in the accumulation of long OPA1 isoforms, as predicted by experiments in yeast (Duvezin-Caubet et al., 2007), but decreases their stability. The accelerated cleavage of OPA1 in the absence of the m-AAA protease is mediated by OMA1, a new member of a conserved and widespread family of membrane-bound M48 metallopeptidases. We have previously identified yeast Oma1 in the mitochondrial inner membrane as a peptidase that can substitute for the function of the m-AAA protease during degradation of a misfolded membrane protein (Käser et al., 2003). Similarly, synthetic growth defects have been observed when mutations in the bacterial AAA protease FtsH were combined with mutations in HtpX, which is a distant homologue of OMA1, indicating overlapping proteolytic activities (Shimohata et al., 2002). In agreement with these findings, we demonstrate in this study that mammalian OMA1, similar to the m-AAA protease, can cleave OPA1. The ...
Metalloendopeptidase OMA1, mitochondrial is an enzyme that in humans is encoded by the OMA1 gene. As a metalloprotease, this protein is a substantial component of the quality control system in the inner membrane of mitochondria. Being activated by enzyme Bax and Bak, mitochondrial protease OMA1 promotes cytochrome c release which subsequently induces apoptosis. The gene OMA1 encodes a metalloprotease, a founding member of a conserved family of membrane-embedded metallopeptidases in mitochondria. The human gene has 9 exons and locates at chromosome band 1p32.2-p32.1 The human protein metalloendopetidase OMA1, mitochondrial is 60.1 kDa in size and composed of 524 amino acids with mitochondrial transition peptide (position 1-13). The mature protein has a theoretical pI of 8.44. The inner membrane of mitochondrial houses two AAA proteases and these membrane-embedded peptidases were termed m- and i-AAA proteases to indicate their different topology in the inner membrane. The m-AAA protease is facing ...
FtSH4 showed a high expression level in the rosette leaves, and its transcript levels were stable during different growth stages (Zhang et al., 2014). These results, combined with the premature senescence phenotype of the ftsh4-4 mutant, indicate that FtSH4 may be an upstream regulator of senescence. Although FtSH4 plays important roles in regulating premature senescence by altering the levels of ROS (Gibala et al., 2009; Kicia et al., 2010; Smakowska et al., 2014, 2016), the detailed mechanism behind this process is not clear. ROS are important multifaceted signaling molecules that can regulate a number of cellular pathways and, thus, play critical roles in plant development (Foyer and Noctor, 2013). ROS and autophagy are associated with cell death, and more recent evidence indicates that both ROS and autophagy play important roles in signaling and cellular adaptation to stress (Wang et al., 2011). Mitochondria are known to play key roles in triggering cell death via altering cellular redox to ...
FtsH is an evolutionary conserved membrane-bound metalloprotease complex. While in most prokaryotes FtsH is encoded by a single gene, multiple FtsH genes are found in eukaryotes. Genetic and biochemical data suggest that the Arabidopsis chloroplast FtsH is a hetero-hexamer. This raises the question why photosynthetic organisms require a heteromeric complex, whereas in most bacteria a homomeric one is sufficient. To gain structural information of the possible complexes, the Arabidopsis FtsH2 (type B) and FtsH5 (type A) were modeled. An in silico study with mixed models of FtsH2/5 suggests that heteromeric hexamer structure with ratio of 4∶2 is more likely to exists. Specifically, calculation of the buried surface area at the interfaces between neighboring subunits revealed that a hetero-complex should be thermodynamically more stable than a homo-hexamer, due to the presence of additional hydrophobic and hydrophilic interactions. To biochemically assess this model, we generated Arabidopsis transgenic

The objective of our study was to investigate the effect of Aliskiren, a renin inhibitor, on the deoxycorticosterone (DOCA) induced myocardial fibrosis in a rat model and its underlying mechanism. A total of 45 Sprague-Dawley (SD) rats underwent right nephrectomy and were randomly assigned into 3 groups: control group (CON group: silicone tube was embedded subcutaneously); DOCA treated group (DOC group: 200 mg of DOCA was subcutaneously administered); DOCA and Aliskiren (ALI) treated group (ALI group: 200 mg of DOCA and 50 mg/kg/d ALI were subcutaneously and intragastrically given, respectively). Treatment was done for 4 weeks. Sirius red staining was employed to detect the expression of myocardial collagen, and the myocardial collagen volume fraction (CVF) and perivascular collagen volume area (PVCA) were calculated. Radioimmunoassay was carried out to measure the renin activity (RA) and content of angiotensin II (Ang II) in the plasma and ventricle. Western blot assay was done to detect the ...
ATP-dependent Clp protease proteolytic subunit (ClpP) is an enzyme that in humans is encoded by the CLPP gene. This protein is an essential component to form the protein complex of Clp protease (Endopeptidase Clp). Enzyme ClpP is a highly conserved serine protease present throughout bacterial and also found in the mitochondria and chloroplasts of eukaryotic cells. The ClpP monomer is folded into three subdomains: the "handle", the globular "head", and the N-terminal region. By itself, ClpP can assemble into a tetradecamer complex (14-members) and form a closed proteolytic chamber. A fully assembled Clp protease complex has a barrel-shaped structure in which two stacked ring of proteolytic subunits (ClpP or ClpQ) are either sandwiched between two rings or single-caped by one ring of ATPase-active chaperon subunits (ClpA, ClpC, ClpE, ClpX or ClpY). ClpXP is presented in almost all bacteria while ClpA is found in the Gram-negative bacteria, ClpC in Gram-Positive bacteria and cyanobacteria. ClpAP, ...
The general pathway involving adenosine triphosphate (ATP)-dependent proteases and ATP-independent peptidases during cytosolic protein degradation is conserved, with differences in the enzymes utilized, in organisms from different kingdoms. Lon and caseinolytic protease (Clp) are key enzymes responsible for the ATP-dependent degradation of cytosolic proteins in Escherichia coli. Orthologs of E. coli Lon and Clp were searched for, followed by multiple sequence alignment of active site residues, in genomes from seventeen organisms, including representatives from eubacteria, archaea, and eukaryotes. Lon orthologs, unlike ClpP and ClpQ, are present in most organisms studied. The roles of these proteases as essential enzymes and in the virulence of some organisms are discussed.
Deg. one of the Escherichia coli systems for degrading abnormal polypeptides (e.g., nonsense fragments), is also involved in the degradation of some classes of missense proteins. Both missense proteins of beta-galactosidase and temperature-sensitive phage products appear to be degraded by the Deg system. Mutations in the Deg system are indistinguishable from mutations classically called lon or capR; all map near proC, all are mucoid, defective in protein degradation, sensitive to radiomimetic agents, and defective in P1 lysogenization. All are able to propagate temperature-sensitive phage better than lon+ parental strains. Mutations that suppress the radiation sensitivity of these strains (sul) also suppress the P1 lysogenization defect, but do not affect mucoidy or the degradation defect.. ...
Lon proteases are distributed in every kingdoms of lifestyle and are necessary for success of cells under tension. absence of bound nucleotide, all six / domains are rotated and out in the way from the L subunits up, which would generate an axial route sufficient to permit unfolded as well as perhaps also small folded XL-888 protein to feed. In every ATP-dependent proteases, substrate gain access to is certainly controlled on the apical surface area of AAA+ domains through axial loops whose positions are transformed in response to rigid area actions as nucleotides bind and so are hydrolysed and released in the AAA+ domains. Multi-component proteases such as for example ClpXP, ClpAP, HslUV (ClpYQ), and 26 S proteasomes, which work as powerful complexes of chaperone and proteolytic elements, control substrate gain access to on the entry towards the protease also. The sequestered proteolytic chambers are built by signing up for two heptamers (or hexamers regarding ClpQ) in person so the energetic ...

N2 - Selective activation of mitoKATP channels can protect the brain or cultured neurons against a variety of anoxic or metabolic challenges. However, little is known about the subunit composition or functional regulation of the channel itself. In the present study, we sought to characterize the mitoKATP channel in the mouse brain using overlapping approaches. First, we determined that mitochondria contain the pore-forming Kir6.1 and Kir6.2 subunits with Western blotting, immunogold electron microscopy and the identification of mitochondrial transport sequences. In contrast, we found no evidence for the presence of either known sulfonylurea receptors (SUR1 or SUR2) in the mitochondria. However, the ...

In mammals, the UPRmt signaling mechanism has been investigated in cell culture models by ethidium bromide treatment (Martinus et al., 1996) and overexpression of aggregation-prone mutant protein ornithine transcarbamylase (OTC) targeted to the mitochondrial matrix (Zhao et al., 2002). Several components of the pathway, such as the mitochondrial chaperones and the quality control protease ClpP were shown to be conserved from C. elegans. However, downstream signaling steps and transcriptional regulation of UPRmt remain not well understood.. In response to unfolded protein stress in mammalian cells, the expression of the nuclear encoded mitochondrial chaperones HSP60, HSP10 and mtDnaJ, and the protease ClpP is induced in a transient manner, the extent of which correlates with the level of unfolded proteins in mitochondria (Zhao et al., 2002). In addition, mitochondrial proteases YME1L1 and PMPCB, the import component TIMM17A and the enzymes NDUFB2, endonuclease G and thioredoxin 2 are all ...

After 2 years at MIT as a research associate, she returned to NIH in 1976 to become a senior investigator in the Laboratory of Molecular Biology, continuing studies on these proteases and their substrates. In collaborations with Michael Maurizi in the Laboratory of Cell Biology at NCI, and Sue Wickner in NCIs Laboratory of Molecular Biology, her laboratory has continued to investigate the ATP-dependent proteases of Escherichia coli and their protein targets, studying the mechanism of proteolysis, the basis for target selection and the ways in which unstable proteins are used in regulatory cascades. The architecture and general mechanism of action of the bacterial proteases and their important role in regulating gene expression have proven to be characteristic not only of E. coli, but of eukaryotic organisms as well. This work led to her election to the National Academy of Sciences in 1998 and the American Academy of Arts and Sciences in 1999. Studies on the role of small RNAs in regulation ...
The calcium-signaling network is an important transducer of internal and external stimuli in plants. These signals are transduced by a divers set of calcium-sensors such as calmodulin and calmodulin like proteins. In this work, AFG1L2 (AFG1 like protein 2) was characterized as a calmodulin binding protein that belongs to the family of AAA+ proteins (ATPases associated with various cellular activities). Using GFP fusion constructs it was possible to determine the in vivo localization of AFG1L2 in mitochondria and also to confirm the dual localization of a previously described homologe, AFG1L1, to mitochondria and chloroplasts. The interaction between AFG1L2 and calmodulin is calcium dependent and the calmodulin binding site of the AFG1L2 protein is in the AAA domain at a site homologous to the AFG1L1 protein, in very close proximity to the Walker A Motif, which is essential for ATP hydrolysis. It could be shown that ATP and ADP intensify the interaction between AFG1L2 and calmodulin. AAA-proteins ...
Introduction Mitochondria are essential organelles present in most eukaryotic cells and typically form discrete structures or elaborate tubular networks in the cytoplasm (1). They were first cytologially characterized as bioblasts by Richard Altmann in 1894. Subsequently, they were renamed into mitochondria by Carl Brenda in 1898. Insight into their structure was provided by the first detailed electron microscopy pictures of these organelles in 1952 (2). It has now been well established that mitochondria fulfill a crucial role in a plethora of biological processes (figure 1 adapted from 3). For example, mitochondria are the main source of cellular ATP production, while they also serve as an important cellular storage for calcium, a key signaling molecule. In this way, mitochondria control calcium levels and thereby regulate calcium-dependent signaling pathways. Additionally, mitochondria participate in maintaining redox homeostasis through their production of reactive oxygen species. These drive ...
In the two cases, intracellular S. aureus USA cells showed clear indicators of ongoing cell division Inhibitors Autophagy is regarded an ancient eukaryotic pathway for cellular self digestion that evolved with the endomembrane strategy . Since the endomembrane system offered an opportunity for invading pathogens to manipulate the host cell, its further thought of the autophagic response to pathogen invasion might have also evolved as an early host defense program of eukaryotic cells . Interestingly enough, this hypothesis explains that autophagy is in portion a stochastic degradation pathway to clear the cytoplasm, therefore securing the performance of each proteins plus the endomembrane technique, but can also be a specific response triggered by certain pressure exposures, such as pathogen invasion. In truth, the autophagic response to pathogen invasion is recognized mainly because autophagy related proteins vital to the stochastic practice of autophagy, this kind of as Atg and LC, have also ...
Broadly, I am interested in studying the pathogenic mechanisms of neurodegenerative diseases. I focus on m-AAA protease, which is present in the inner mitochondrial membrane and is involved in protein quality control. In mammals, it exists as a hetero-oligomeric complex composed of two subunits, paraplegin and AFG3L2, and as a homo-oligomeric complex composed of AFG3L2 alone. Mutations in AFG3L2 lead to autosomal dominant spinocerebellar ataxia, SCA 28, while mutations in another subunit, paraplegin, leads to hereditary spastic paraplegia. The m-AAA protease is one of the many instances where there is an intricate connection between mitochondria and neurodegenerative diseases. I attempt to study the mitochondrial dynamics and transport in the neurons of AFG3L2 knock out mouse in vitro to arrive at a plausible explanation for neurodegenerative mechanisms.. ...

We report the identification of disruptions in 19 genes and one intergenic mutation that negatively affect biofilm formation in S. aureus. With the exception of multiple insertions in each gene of the icaADBC operon, we uncovered none of the genes previously described for their role in biofilm formation in staphylococci. For example, we did not identify Em-Mu insertions in genes encoding subunits of the Clp ATP-dependent proteases, rbf, sarA, dtlA, atlE, hla, and rsbU. Our screen was large but not saturating, and other biofilm-defective mutants await identification. We do not report a screen for increased biofilm formation with S30. Interestingly, a recent study describes such an increased biofilm screen in another S. aureus human clinical isolate and points to the discovery of an ica-independent biofilm pathway active in the absence of the ArlRS two-component sensor (67).. Three mutations were functionally complemented for their biofilm defect by reintroducing cloned genes coding for MgrA, ...

Alternatively, YME1L degradation could decrease the capacity for cells to regulate inner membrane proteostasis. To explore this potential consequence of YME1L degradation, we monitored the impact of oxidative stress on YME1L‐mediated regulation of the TIM23 mitochondrial protein import complex [30]. Mammalian TIM23 forms two exclusive complexes containing distinct core interactions between the subunit Tim23 and one of the two mammalian paralogs of yeast Tim17, Tim17A, or Tim17B [31]. Previous work showed that Tim17A is a stress‐regulated TIM23 subunit that is rapidly degraded by YME1L in response to eIF2α phosphorylation‐dependent translational attenuation [30]. However, Tim17B is not subject to this regulation. Thus, YME1L‐mediated degradation of Tim17A reduces the population of active TIM23 complexes containing a core Tim23-Tim17A interaction without impacting TIM23 complexes containing a core Tim23-Tim17B interaction [30]. This provides a mechanism for cells to sensitively attenuate, ...
