Atypical chemokine receptor 1 (ACKR1) is a G protein-coupled receptor (GPCR) targeted by <i>Staphylococcus aureus</i> bicomponent pore-forming leukotoxins to promote bacterial growth and immune evasion. Here, we have developed an integrative molecular pharmacology and structural biology approach in order to characterize the effect of leukotoxins HlgA and HlgB on ACKR1 structure and function. Interestingly, using cell-based assays and native mass spectrometry, we found that both components HlgA a ...[more]

HDX-MS Analysis of CD47 Conformational Dynamics

Project description:CD47 is the only 5-transmembrane (5-TM) spanning receptor of the immune system. Its extracellular domain (ECD) is a cell surface ‘marker of self’ that binds SIRPα and inhibits macrophage phagocytosis, and cancer immuno-therapy approaches in clinical trials are focused on blocking CD47/SIRPα interaction. Using hydrogen-deuterium exchange we show that CD47’s ECLR architecture, comprised of two extracellular loops and the SWF loop, creates a molecular environment stabilizing the ECD for presentation on the cell surface.

LptM promotes oxidative maturation of the lipopolysaccharide translocon by substrate binding mimicry.

Project description:Insertion of lipopolysaccharide (LPS) into the outer membrane (OM) of Gram-negative bacteria is mediated by a druggable OM translocon consisting of a beta-barrel membrane protein, LptD, and a lipoprotein, LptE. The beta-barrel assembly machinery (BAM) assembles LptD together with LptE to form a plug-and-barrel structure. In the enterobacterium Escherichia coli, formation of two native disulfide bonds in LptD controls LPS translocon activation. Here we report the discovery of LptM (formerly YifL), a conserved lipoprotein that assembles together with LptD and LptE at the BAM complex. We demonstrate that LptM stabilizes a conformation of LptD that can efficiently acquire native disulfide bonds and be released as mature LPS translocon by the BAM complex. Inactivation of LptM causes the accumulation of non-natively oxidized LptD, making disulfide bond isomerization by DsbC become essential for viability. Our structural prediction and biochemical analyses indicate that LptM binds to sites in both LptD and LptE that are proposed to coordinate LPS insertion into the OM. These results suggest that, by mimicking LPS binding, LptM facilitates oxidative maturation of LptD, thereby activating the LPS translocon.

HDX-MS of CSN-CRL2 complexes - Structural basis of Cullin 2 RING E3 ligase regulation by the COP9 signalosome

Project description:Cullin-Ring E3 Ligases (CRLs) regulate a multitude of cellular pathways through specific substrate receptors. The COP9 signalosome (CSN) deactivates CRLs by removing NEDD8 (N8) from activated Cullins. The structure of stable CSN-CRL can be used to understand this mechanism of regulation. Here we present the first structures of the neddylated and deneddylated CSN-CRL2 complexes by combining single particle cryo-electron microscopy (cryo-EM) with chemical cross-linking mass spectrometry (MS). These structures reveal a conserved mechanism of CSN activation, consisting of conformational clamping of the CRL2 substrate by CSN2/CSN4, release of the catalytic CSN5/CSN6 heterodimer and finally activation of the CSN5 deneddylation machinery. Using hydrogen deuterium exchange-MS we show that CRL2 binding and conformational activation of CSN5/CSN6 occur in a neddylation-independent manner. The presence of NEDD8 is required to activate the CSN5 active site. Overall, by synergising cryo-EM with MS, we identified novel sensory regions of the CSN that mediate its stepwise activation mechanism and provide a framework for better understanding the regulatory mechanism of other Cullin family members.

Substrate-induced conformational dynamics of the dopamine transporter

Project description:The dopamine transporter is a member of the neurotransmitter:sodium symporters (NSSs), which are responsible for termination of neurotransmission through Na+-driven reuptake of neurotransmitter from the extracellular space. Experimental evidence elucidating the coordinated conformational rearrangements related to the transport mechanism has so far been limited. Here we probe the global Na+- and dopamine-induced conformational dynamics of the wild-type Drosophila melanogaster dopamine transporter using hydrogen-deuterium exchange mass spectrometry. We identify Na+- and dopamine-induced changes in specific regions of the transporter, suggesting their involvement in protein conformational transitions. Furthermore, we detect ligand-dependent slow cooperative fluctuations of helical stretches in several domains of the transporter, which could be a molecular mechanism that assists in the transporter function. Our results provide a framework for understanding the molecular mechanism underlying the function of NSSs by revealing detailed insight into the state-dependent conformational changes associated with the alternating access model of the dopamine transporter.

Unravelling the mechanism of neurotensin recognition by neurotensin receptor 1

Project description:The conformational ensembles of G-protein coupled receptors (GPCRs) include inactive and active states. Spectroscopy techniques, including NMR, show that agonists, antagonists and other ligands shift the ensemble toward specific states depending on the pharmacological efficacy of the ligand. How receptors recognize ligands and the kinetic mechanism underlying this population shift is poorly understood. Here, we investigate the kinetic mechanism of neurotensin recognition by neurotensin receptor 1 (NTS1) using 19F-NMR, hydrogen-deuterium exchange mass spectrometry and stopped-flow fluorescence spectroscopy. Our results indicate slow-exchanging conformational heterogeneity on the extracellular surface of ligand-bound NTS1. Numerical analysis of the kinetic data of neurotensin binding to NTS1 shows that ligand recognition follows an induced fit mechanism, in which conformational changes occur after neurotensin binding. This approach is applicable to other GPCRs to provide insight into the kinetic regulation of ligand recognition by GPCRs.

Conformational restriction shapes the inhibition of a multidrug efflux adaptor protein

Project description:Membrane efflux pumps play a major role in bacterial multidrug resistance. The tripartite multidrug efflux pump system from Escherichia coli, AcrAB-TolC, is a target for inhibition to lessen resistance development and restore antibiotic efficacy, with homologs in other ESKAPE pathogens. Here, we rationalize a mechanism of inhibition against the periplasmic adaptor protein, AcrA, using a combination of hydrogen/deuterium exchange mass spectrometry, cellular efflux assays, and molecular dynamics simulations. We define the structural dynamics of AcrA and find that an inhibitor can inflict long-range stabilisation across all four of its domains, whereas an interacting efflux substrate has minimal effect. Our results support a model where an inhibitor forms a molecular wedge within a cleft between the lipoyl and αβ domains of AcrA, diminishing its conformational transmission of drug-evoked signals from AcrB to TolC. This work provides molecular insights into multidrug adaptor protein function which could be valuable for developing antimicrobial therapeutics.

Eukaryotic Ribosome GCN2 interaction Hydrogen/Deuterium Exchange Mass Spectrometry

Project description:General control nonderepressible 2 (GCN2) phosphorylates eIF2α, regulating translation in response to nutritional stress. Here, we show that mammalian ribosomes are potent GCN2 activators. Hydrogen/deuterium exchange–mass spectrometry (HDX-MS) showed GCN2 interacting with domain II of the uL10 P-stalk protein. The P-stalk is a uL10/P12/P22 pentameric complex that is part of the ribosomal GTPase-associated center. Recombinant human P-stalk greatly stimulates GCN2. Both domain II of uL10 and the C-terminal tails of P1 and P2 are necessary for maximal GCN2 activation. On actively translating ribosomes, the C-terminal tails of P1 and P2 are sequestered by elongation factors, suggesting P-stalk availability could link translational stress to GCN2 activation.

The structural dynamics of full length divisome transmembrane proteins FtsQ, FtsB, and FtsL in FtsQBL complex formation

Project description:Bacterial divisome is a group of proteins governing cell division. Out of the 15 critical proteins in Escherichia coli, the transmembrane protein complex FtsQBL plays an essential role in regulating the action. Although extensive efforts have been made, there is limited information regarding the interaction within this three-member complex. Here, HDX-MS was used to study the dynamic change of the full-length protein FtsQ, FtsB, and FtsL. Direct experimental evidence shows that FtsB and FtsL form a stable complex by the transmembrane and periplasmic regions. After the complex formation, the structural feature in FtsB properly becomes more defined. This transition may also bring the constriction control domains (CCDs) close to the one in FtsL. Furthermore, with the helical interaction between two proteins, the CCDs have a more determined location relative to the membrane surface. On the other hand, the FtsQ in the FtsQBL complex showed rigidity enhancement in two regions. The interaction with FtsB would fix a significant portion of the FtsQ β-domains. Interestingly, the formation of the FtsQBL complex also stiffens the sequence connecting the two domains in FtsQ. Overall, this study provides important experimental evidence on the conformational dynamic change of the FtsQ, FtsB, and FtsL upon the complex formation and insights into the FtsQBL function in the divisome.

The dopamine transporter antiports potassium to increase the uptake of dopamine

Project description:The dopamine transporter facilitates dopamine reuptake from the extracellular space to terminate neurotransmission. The transporter belongs to the neurotransmitter:sodium symporter family, which includes transporters for serotonin, norepinephrine, and GABA that utilize the Na+ gradient to drive the uptake of substrate. Decades ago, it was shown that the serotonin transporter also antiports K+, but investigations of K+-coupled transport in other neurotransmitter:sodium symporters have been inconclusive. Here, we show that ligand binding to the drosophila- and human dopamine transporters are inhibited by K+, and the conformational dynamics of the drosophila dopamine transporter in K+ are divergent from the apo- and Na+-states. Furthermore, we found that K+ increased dopamine uptake by the drosophila dopamine transporter in liposomes, and visualized Na+ and K+ fluxes in single proteoliposomes using fluorescent ion indicators. Our results expand on the fundamentals of dopamine transport and prompt a reevaluation of the impact of K+ on other transporters in this pharmacologically important family.
