Abstract
A new generation of affinity-based probes (AfBPs) has been developed to label and identity matrix metalloproteinases (MMPs) under their active form in complex proteomes. First, the probe reacts with an active MMP through a proximity-driven reaction that does not require any external trigger. Following this affinity-labeling step, a streptavidin-based enrichment of the resulting biotin-tagged MMP is carried out. Finally, after on-beads proteolytic digestion by trypsin, MMP signature peptides are analyzed and identified by mass spectrometry. Such a "photoactivation-free" labeling can be applied to the detection of several MMPs in a wide variety of biological systems, including in vivo conditions.

Abstract
CD95L (also known as FasL or CD178) is a member of the tumor necrosis family (TNF) superfamily. Although this transmembrane ligand has been mainly considered as a potent apoptotic inducer in CD95 (Fas)-expressing cells, more recent studies pointed out its role in the implementation of non-apoptotic signals. Accordingly, this ligand has been associated with the aggravation of inflammation in different auto-immune disorders and in the metastatic occurrence in different cancers. Although it remains to decipher all key factors involved in the ambivalent role of this ligand, accumulating clues suggest that while the membrane bound CD95L triggers apoptosis, its soluble counterpart generated by metalloprotease-driven cleavage is responsible for its non-apoptotic functions. Nonetheless, the metalloproteases (MMPs and ADAMs) involved in the CD95L shedding, the cleavage sites and the different stoichiometries and functions of the soluble CD95L remain to be elucidated. To better understand how soluble CD95L triggers signaling pathways from apoptosis to inflammation or cell migration, we propose herein to summarize the different metalloproteases that have been described to be able to shed CD95L, their cleavage sites and the biological functions associated with the released ligands. Based on these new findings, the development of CD95/CD95L-targeting therapeutics is also discussed.

Abstract
Activity-based probes enable discrimination between the active enzyme and its inactive or inactivated counterparts. Since metalloproteases catalysis is non-covalent, activity-based probes targeting them have been systematically developed by decorating reversible inhibitors with photo-crosslinkers. By exploiting two types of ligand-guided chemistry, we identified novel activity-based probes capable of covalently modifying the active site of matrix metalloproteases (MMPs) without any external trigger. The ability of these probes to label recombinant MMPs was validated in vitro and the identity of the main labelling sites within their S3 ' region unambiguously assigned. We also demonstrated that our affinity probes can react with rhMMP12 at nanogram scale (that is, at 0.07 % (w/w)) in complex proteomes. Finally, this ligand-directed chemistry was successfully applied to label active MMP-12 secreted by eukaryote cells. We believe that this approach could be transferred more widely to many other metalloproteases, thus contributing to tackle their unresolved proteomic profiling in vivo.

Abstract
Saw et al. show via the combinatorial deletion of Timp family members in mice that metalloprotease regulation of FGF-2 is a crucial event in the chondrocyte maturation program, underlying the growth plate development and bone elongation responsible for attaining proper body stature. Regulated growth plate activity is essential for postnatal bone development and body stature, yet the systems regulating epiphyseal fusion are poorly understood. Here, we show that the tissue inhibitors of metalloprotease (TIMP) gene family is essential for normal bone growth after birth. Whole-body quadruple-knockout mice lacking all four TIMPs have growth plate closure in long bones, precipitating limb shortening, epiphyseal distortion, and widespread chondrodysplasia. We identify TIMP/FGF-2/IHH as a novel nexus underlying bone lengthening where TIMPs negatively regulate the release of FGF-2 from chondrocytes to allow IHH expression. Using a knock-in approach that combines MMP-resistant or ADAMTS-resistant aggrecans with TIMP deficiency, we uncouple growth plate activity in axial and appendicular bones. Thus, natural metalloprotease inhibitors are crucial regulators of chondrocyte maturation program, growth plate integrity, and skeletal proportionality. Furthermore, individual and combinatorial TIMP-deficient mice demonstrate the redundancy of metalloprotease inhibitor function in embryonic and postnatal development.

Abstract
Matrix metalloproteases (MMPs) have attracted considerable attention as critical mediators of pathological tissue remodeling processes. However it remains an unresolved challenge to detect their active forms in biological samples. To prove the efficacy of a recently developed MMP activity-based probe, we examined the content in MMP active forms of bronchoalveolar lavage fluids (BALf) from male C57BL/6 mice exposed to ultrafine carbon black nanoparticles, a model of chronic obstructive pulmonary disease. This probe was shown to label proteins, mostly expressed in BALf of mice exposed to nanoparticles. Using competition assays with a selective MMP-12 inhibitor as well as MMP-12 knock-out mice, one of these proteins was identified as the active form of the catalytic domain of MMP-12. This new probe can detect the active form of MMP-12 down to a threshold of 1 fmol. Radioactive counting showed the concentration of the active form of MMP-12 to be around 1 fmol/μl in BALf from nanoparticle-treated mice. A less sensitive probe would therefore not have detected MMP-12. As the probe can detect other MMPs in the femtomolar range, it is a potentially powerful tool for monitoring the levels of MMP active forms in various diseases.

Abstract
Detecting the active forms of proteases by using activity-based probes in complex proteomes has become an intensively investigated field of research over the past years because many pathogenic conditions involve alterations in protease activities. The detection of lysosomal cysteine proteases, the cathepsins, has mostly relied on the use of probes that incorporate reactive electrophilic moieties to modify a cysteine in the active site covalently. Here we report the first example of an activity-based probe that targets the cathepsins and incorporates a photoactivatable benzophenone group for covalent labelling. When tested on a set of five cathepsins (B, K, L, S and V), this probe selectively labelled the active site of cathepsin L. Furthermore, when tested on crude cell extracts, the probe specifically detected cathepsin L quantities as low as a few picomoles. This study suggests that photoaffinity labelling is a promising approach for developing highly selective and useful cathepsin L probes. In particular, this probe might allow the detection of small amounts of the secreted active cathepsin L form in the cellular microenvironment in vitro and ex vivo.

Abstract
Clostridium botulinum neurotoxin type A (BoNT/A) is one of the most potent toxins for humans and a major biothreat agent. Despite intense chemical efforts over the past 10 years to develop inhibitors of its catalytic domain (catBoNT/A), highly potent and selective inhibitors are still lacking. Recently, small inhibitors were reported to covalently modify catBoNT/A by targeting Cys(165), a residue located in the enzyme active site just above the catalytic zinc ion. However, no direct proof of Cys(165) modification was reported, and the poor accessibility of this residue in the x-ray structure of catBoNT/A raises concerns about this proposal. To clarify this issue, the functional role of Cys(165) was first assessed through a combination of site-directed mutagenesis and structural studies. These data suggested that Cys(165) is more involved in enzyme catalysis rather than in structural property. Then by peptide mass fingerprinting and x-ray crystallography, we demonstrated that a small compound containing a sulfonyl group acts as inhibitor of catBoNT/A through covalent modification of Cys(165). The crystal structure of this covalent complex offers a structural framework for developing more potent covalent inhibitors catBoNT/A. Other zinc metalloproteases can be founded in the protein database with a cysteine at a similar location, some expressed by major human pathogens; thus this work should find broader applications for developing covalent inhibitors.

Abstract
Various attempts to detect matrix metalloproteinase (MMP) active forms from complex proteomes, based on the use of specific photoactivatable affinity probes, have up to now failed. To overcome this failure, an affinity approach has been evaluated as an alternative to the photoaffinity one. For this purpose, two probes were synthesized to interact specifically with the active site of MMPs and allow isolation of MMP/probe complexes on magnetic beads through a biotin linker. Using phosphinic peptide chemistry, we prepared an affinity probe displaying picomolar potency toward several MMPs, and a related photoaffinity probe incorporating a photoactivatable azido group exhibiting subnanomolar affinity toward these targets. By a combination of silver-staining detection and MALDI peptide mass fingerprints, a systematic comparison was made of both strategies in terms of hMMP-12 and hMMP-8 recovery and identification when present in mixtures of different complexity. The results obtained show that the affinity protocol is superior to the photoaffinity strategy in terms of quantity of captured MMPs and number of MMP tryptic fragments detected in MALDI-MS. The specificity and efficiency of the affinity capture protocol developed in this study allowed easy, fast, and unambiguous detection by MALDI-MS of three hMMPs (2, 8, and 12), from a single affinity capture experiment, when added (10-36 ng of MMPs) to a tumor extract (10 microg). Thus, the tools and approaches reported should enable us to progress in the detection of endogenous active forms of MMPs in complex proteomes, an important objective with many diagnostic applications.

Abstract
Mass spectroscopy, microsequencing, and site-directed mutagenesis studies have been performed to identify in human matrix metalloelastase (hMMP-12) residues covalently modified by a photoaffinity probe, previously shown to be able to covalently label specifically the active site of matrix metalloproteinases (MMPs). Results obtained led us to conclude that photoactivation of this probe in complex with hMMP-12 affects a single residue in human MMP-12, Lys(241), through covalent modification of its side chain epsilon NH(2) group. Because x-ray and NMR studies of hMMP-12 indicate that Lys(241) side chain is highly flexible, our data reveal the existence of particular Lys(241) side-chain conformation in which the epsilon NH(2) group points toward the photolabile group of the probe, an event explaining the high levels of cross-linking yield between hMMP-12 and the probe. Lys(241) is not conserved in MMPs, thus differences in cross-linking yields observed with this probe between MMP members may be linked to the residue variability observed at position 241 in this family.

Abstract
Intact noncovalent complexes were studied in the gas phase using negative ion nano-ESI mass spectrometry. Among various noncovalent systems studied in the gas phase, the interaction of DNA strands with peptide nucleic acids (PNAs) presents a strong interest as biologically relevant systems. PNAs originally described by Nielsen are used as DNA mimics as possible medical agents by imprisoning DNA single strands into stable noncovalent complexes. Two types of PNAs were investigated in the PNA/DNA multiplex: the original Nielsen's PNA and a modified backbone PNA by the introduction of syn- and anti-(aminoethyl)thiazolidine rings. We first investigated the stoichiometry of PNA/DNA multiplexes formed in solution and observed them in the gas phase via qualitative kinetics of complementary strand associations. It resulted in observing PNA2/DNA triplexes (ts) as the multiply deprotonated species, most stable in both the solution and gas phase. Second, charge-dependant decompositions of these species were undertaken under low-energy collision conditions. It appears that covalent bond cleavages (base releasing or skeleton cleavage) occur from lower ts charge states rather than ts unzipping, which takes place from higher charge states. This behavior can be explained by considering the presence of zwitterions depending on the charge state. They result in strong salt-bridge interactions between the positively charged PNA side chain and the negatively charged DNA backbone. We propose a general model to clearly display the involved patterns in the noncovalent triplex decompositions. Third, the relative stability of three PNA2/DNA complexes was scrutinized in the gas phase by acquiring the breakdown curves of their ts(6-) form, corresponding to the ts unzipping. The chemical structures of the studied PNAs were chosen in order to evidence the possible influence of backbone stereochemistry on the rigidity of PNA2/DNA complexes. It provided significantly different stabilities via V(m) measurements. The relative gas-phase stability order obtained was compared to that found in solution by Chassaing et al., and shows qualitative agreement.

Abstract
[structure: see text] Lanthionine, a thioether analogue of cystine, is a key component of the lantibiotics, a family of modified peptides bearing multiple thioether bridges resulting from posttranslational modifications between side chains. It is also used as a conformational constraint in medicinally active peptides. We have explored two synthetic routes to give lanthionine, orthogonally protected with Alloc/allyl and Fmoc groups. One route utilized a carbamate-protected iodoalanine that yielded a mixture of diastereoisomers, and one utilized a trityl-protected iodoalanine, formed via a Mitsunobu reaction, that gave the single desired lanthionine, in complete regio- and diastereoselectivity. We then used this orthogonally protected lanthionine in the solid-phase synthesis of an analogue of a fragment of nisin containing its ring C. The chemoselective deprotection of the allyl and Alloc groups of the incorporated lanthionine unit was followed by regio- and stereoselective cyclization on resin to give the desired lanthionine-bridged peptide.

Abstract
Synthetic approaches to the lantibiotics, a family of thioether-bridged antimicrobial peptides, require flexible synthetic routes to a variety of orthogonally protected derivatives of lanthionine 1. The most direct approaches to lanthionine involve the reaction of cysteine with an alanyl beta-cation equivalent. Several possibilities exist for the alanyl beta-cation equivalent, including direct activation of serine under Mitsunobu conditions: however, the low reactivity of sulfur nucleophiles in the Mitsunobu reaction has previously precluded its use in the synthesis of the lantibiotics. We report here a new approach to the synthesis of protected lanthionine, using a novel variant of the Mitsunobu reaction in which catalytic zinc tartrate is used to enhance the nucleophilicity of the thiol. In the course of these studies, we have also demonstrated that the synthesis of lanthionine from trityl-protected beta-iodoalanines is prone to rearrangement, via an aziridine, to give predominantly trityl-protected alpha-iodo-beta-alanines, and hence norlanthionines, as the major products.
