Nature communications 20200311 1

Lipin/Pah phosphatidic acid phosphatases (PAPs) generate diacylglycerol to regulate triglyceride synthesis and cellular signaling. Inactivating mutations cause rhabdomyolysis, autoinflammatory disease, and aberrant fat storage. Disease-mutations cluster within the conserved N-Lip and C-Lip regions that are separated by 500-residues in humans. To understand how the N-Lip and C-Lip combine for PAP function, we determined crystal structures of Tetrahymena thermophila Pah2 (Tt Pah2) that directly fu ...[more]

HDX analysis of PI3K oncogenic mutants

Project description:We used Hydrogen-Deuterium Exchange Mass Spectrometry (HDX-MS) to examine the dynamic structural changes caused by oncogenic mutations. We performed HDX-MS comparing the full-length complex against the catalytic core which suggest that addition of pY leads to mixed two state population where the state 1 consists of iSH2 bound p110α and the state 2 consists of p110α where the iSH2 is completely disengaged.Therefore, we propose that the non-kinase domain mutations push the equilibrium towards state 2 leading to enhanced enzyme activity.We also propose that the kinase domain mutations lead to the re-orientation of the c-terminal tail leading to exposure of the activation loop and enhanced membrane binding.

HDX-MS of TRAPPII reveals a conserved Rab binding interface

Project description:We used hydrogen deuterium exchange mass spectrometry (HDX-MS) to define the interface of TRAPPII with three Rab GTPases (Rab1, Rab11, Rab43). These experiments were performed in the presence of EDTA to generate a nucleotide free stabilised Rab-GEF complex. Significant decreases in deuterium incorporation (defined as >4%, >0.4Da, two tailed T-test p value <0.01) were identified in the TRAPPC2L, TRAPPC4, and TRAPPC5 in the presence of Rab GTPases with no other changes in other TRAPP subunits. Here we show that all three Rab GTPases bind at a conserved interface of TRAPPII.

HDX-MS of AcrIF9 and AcrIF2 binding to CRISPR IF Csy complex

Project description:CRISPR RNA-guided detection and degradation of foreign DNA is a dynamic process. Viruses can interfere with this cellular defense by expressing small proteins called anti-CRISPRs. While structural models of anti-CRISPRs bound to their target complex provide static snapshots that inform mechanism, the dynamics and thermodynamics of these interactions are often overlooked. Here we use hydrogen deuterium exchange-mass spectrometry (HDX-MS) and differential scanning fluorimetry (DSF) experiments to determine how anti-CRISPR binding impacts the conformational landscape of the type IF CRISPR RNA guided surveillance complex (Csy) upon binding of two different anti-CRISPR proteins (AcrIF9 and AcrIF2). The results demonstrate that AcrIF2 binding relies on enthalpic stabilization, whereas AcrIF9 uses an entropy driven reaction to bind the CRISPR RNA-guided surveillance complex. Collectively, this work reveals the thermodynamic basis and mechanistic versatility of anti-CRISPR-mediated immune suppression. More broadly, this work presents a striking example of how allosteric effectors are employed to regulate nucleoprotein complexes.

Investigating the conformational changes of OEA on HIF-3A-ARNT by HDX-MS

Project description:We used hydrogen-deuterium exchange mass spectrometry (HDX-MS) to investigate the influence of OEA on HIF-3A-ARNT.HDX-MS data indicated that OEA binding stabilized multiple residues within the Gβ and Fα regions of HIF-3A PAS-B domain.It is possible that the stabilized Gβ and Fα function as an “interlayer” to further contact with the AB-loop of ARNT.

HDX-MS studies of the bacterial multidrug ABC transporter BmrA in presence or absence of a ligand (rhodamine-6G)

Project description:Multidrug ATP-Binding Cassette (ABC) exporters use an alternating access mechanism to translocate drugs across membranes, but the molecular mechanism of substrate release is still elusive due to the poor affinity of the drug-binding pocket for its ligand at this stage. Here, we bring new information on this mechanism by resolving two ATP-bound outward-facing conformations of the homodimer BmrA from Bacillus subtilis by X-ray crystallography with no drug bound and by cryo-EM in the presence of rhodamine 6G. This revealed the first structure of a multidrug pump with a substrate bound to the drug-binding pocket in a pre-release state. Two R6G molecules bind to the drug-binding cavity at the level of the outer leaflet, between transmembrane (TM) helices 1-2 of one monomer and TM5’-6’ of the other. Hydrogen-Deuterium exchange coupled to mass spectrometry (HDX-MS) and molecular dynamics simulations confirmed the high flexibility of this region, presumably driving the release of structurally divergent compounds.
