Native mass spectrometry goes more native: investigation of membrane protein complexes directly from SMALPs.

ABSTRACT: Other than more widely used methods, the use of styrene maleic acid allows the direct extraction of membrane proteins from the lipid bilayer into SMALPs keeping it in its native lipid surrounding. Here we present the combined use of SMALPs and LILBID-MS, allowing determination of oligomeric states of membrane proteins of different functionality directly from the native nanodiscs.

Protein assemblies ejected directly from native membranes yield complexes for mass spectrometry.

Project description:Membrane proteins reside in lipid bilayers and are typically extracted from this environment for study, which often compromises their integrity. In this work, we ejected intact assemblies from membranes, without chemical disruption, and used mass spectrometry to define their composition. From Escherichia coli outer membranes, we identified a chaperone-porin association and lipid interactions in the β-barrel assembly machinery. We observed efflux pumps bridging inner and outer membranes, and from inner membranes we identified a pentameric pore of TonB, as well as the protein-conducting channel SecYEG in association with F1FO adenosine triphosphate (ATP) synthase. Intact mitochondrial membranes from Bos taurus yielded respiratory complexes and fatty acid-bound dimers of the ADP (adenosine diphosphate)/ATP translocase (ANT-1). These results highlight the importance of native membrane environments for retaining small-molecule binding, subunit interactions, and associated chaperones of the membrane proteome.

Scratching the surface: native mass spectrometry of peripheral membrane protein complexes.

Project description:A growing number of integral membrane proteins have been shown to tune their activity by selectively interacting with specific lipids. The ability to regulate biological functions via lipid interactions extends to the diverse group of proteins that associate only peripherally with the lipid bilayer. However, the structural basis of these interactions remains challenging to study due to their transient and promiscuous nature. Recently, native mass spectrometry has come into focus as a new tool to investigate lipid interactions in membrane proteins. Here, we outline how the native MS strategies developed for integral membrane proteins can be applied to generate insights into the structure and function of peripheral membrane proteins. Specifically, native MS studies of proteins in complex with detergent-solubilized lipids, bound to lipid nanodiscs, and released from native-like lipid vesicles all shed new light on the role of lipid interactions. The unique ability of native MS to capture and interrogate protein-protein, protein-ligand, and protein-lipid interactions opens exciting new avenues for the study of peripheral membrane protein biology.

Combining Mass Spectrometry and X-Ray Crystallography for Analyzing Native-Like Membrane Protein Lipid Complexes.

Project description:Membrane proteins represent a challenging family of macromolecules, particularly related to the methodology aimed at characterizing their three-dimensional structure. This is mostly due to their amphipathic nature as well as requirements of ligand bindings to stabilize or control their function. Recently, Mass Spectrometry (MS) has become an important tool to identify the overall stoichiometry of native-like membrane proteins complexed to ligand bindings as well as to provide insights into the transport mechanism across the membrane, with complementary information coming from X-ray crystallography. This perspective article emphasizes MS findings coupled with X-ray crystallography in several membrane protein lipid complexes, in particular transporters, ion channels and molecular machines, with an overview of techniques that allows a more thorough structural interpretation of the results, which can help us to unravel hidden mysteries on the membrane protein function.

Mass spectrometry of intact membrane protein complexes.

Project description:Mass spectrometry (MS) of intact soluble protein complexes has emerged as a powerful technique to study the stoichiometry, structure-function and dynamics of protein assemblies. Recent developments have extended this technique to the study of membrane protein complexes, where it has already revealed subunit stoichiometries and specific phospholipid interactions. Here we describe a protocol for MS of membrane protein complexes. The protocol begins with the preparation of the membrane protein complex, enabling not only the direct assessment of stoichiometry, delipidation and quality of the target complex but also the evaluation of the purification strategy. A detailed list of compatible nonionic detergents is included, along with a protocol for screening detergents to find an optimal one for MS, biochemical and structural studies. This protocol also covers the preparation of lipids for protein-lipid binding studies and includes detailed settings for a quadrupole time-of-flight (Q-TOF) mass spectrometer after the introduction of complexes from gold-coated nanoflow capillaries.

Standard Proteoforms and Their Complexes for Native Mass Spectrometry.

Project description:Native mass spectrometry (nMS) is a technique growing at the interface of analytical chemistry, structural biology, and proteomics that enables the detection and partial characterization of non-covalent protein assemblies. Currently, the standardization and dissemination of nMS is hampered by technical challenges associated with instrument operation, benchmarking, and optimization over time. Here, we provide a standard operating procedure for acquiring high-quality native mass spectra of 30-300 kDa proteins using an Orbitrap mass spectrometer. By describing reproducible sample preparation, loading, ionization, and nMS analysis, we forward two proteoforms and three complexes as possible standards to advance training and longitudinal assessment of instrument performance. Spectral data for five standards can guide assessment of instrument parameters, data production, and data analysis. By introducing this set of standards and protocols, we aim to help normalize native mass spectrometry practices across labs and provide benchmarks for reproducibility and high-quality data production in the years ahead.

Native mass spectrometry characterization of intact nanodisc lipoprotein complexes.

Project description:We describe here the analysis of nanodisc complexes by using native mass spectrometry (MS) to characterize their molecular weight (MW) and polydispersity. Nanodiscs are nanoscale lipid bilayers that offer a platform for solubilizing membrane proteins. Unlike detergent micelles, nanodiscs are native-like lipid bilayers that are well-defined and potentially monodisperse. Their mass spectra allow peak assignment based on differences in the mass of a single lipid per complex. Resultant masses agree closely with predicted values and demonstrate conclusively the narrow dispersity of lipid molecules in the nanodisc. Fragmentation with collisionally activated dissociation (CAD) or electron-capture dissociation (ECD) shows loss of a small number of lipids and eventual collapse of the nanodisc with release of the scaffold protein. These results provide a foundation for future studies utilizing nanodiscs as a platform for launching membrane proteins into the gas phase.

Generation of Charge-Reduced Ions of Membrane Protein Complexes for Native Ion Mobility Mass Spectrometry Studies.

Project description:Recent advances in native mass spectrometry (MS) have enabled the elucidation of how small molecule binding to membrane proteins modulates their structure and function. The protein-stabilizing osmolyte, trimethylamine oxide (TMAO), exhibits attractive properties for native MS studies. Here, we report significant charge reduction, nearly threefold, for three membrane protein complexes in the presence of this osmolyte without compromising mass spectral resolution. TMAO improves the ability to resolve individual lipid-binding events to the ammonia channel (AmtB) by over 200% compared to typical native conditions. The generation of ions with compact structure and access to a larger number of lipid-binding events through the incorporation of TMAO increases the utility of IM-MS for structural biology studies.

Native Ambient Mass Spectrometry of an Intact Membrane Protein Assembly and Soluble Protein Assemblies Directly from Lens Tissue.

Project description:Membrane proteins constitute around two-thirds of therapeutic targets but present a significant challenge for structural analysis due to their low abundance and solubility. Existing methods for structural analysis rely on over-expression and/or purification of the membrane protein, thus removing any links back to actual physiological environment. Here, we demonstrate mass spectrometry analysis of an intact oligomeric membrane protein directly from tissue. Aquaporin-0 exists as a 113 kDa tetramer, with each subunit featuring six transmembrane helices. We report the characterisation of the intact assembly directly from a section of sheep eye lens without sample pre-treatment. Protein identity was confirmed by mass measurement of the tetramer and subunits, together with top-down mass spectrometry, and the spatial distribution was determined by mass spectrometry imaging. Our approach allows simultaneous analysis of soluble protein assemblies in the tissue.

Characterization of native protein complexes using ultraviolet photodissociation mass spectrometry.

Project description:Ultraviolet photodissociation (UVPD) mass spectrometry (MS) was used to characterize the sequences of proteins in native protein-ligand and protein-protein complexes and to provide auxiliary information about the binding sites of the ligands and protein-protein interfaces. UVPD outperformed collisional induced dissociation (CID), higher-energy collisional dissociation (HCD), and electron transfer dissociation (ETD) in terms of yielding the most comprehensive diagnostic primary sequence information about the proteins in the complexes. UVPD also generated noncovalent fragment ions containing a portion of the protein still bound to the ligand which revealed some insight into the nature of the binding sites of myoglobin/heme, eIF4E/m(7)GTP, and human peptidyl-prolyl cis-trans isomerase 1 (Pin1) in complex with the peptide derived from the C-terminal domain of RNA polymerase II (CTD). Noncovalently bound protein-protein fragment ions from oligomeric ?-lactoglobulin dimers and hexameric insulin complexes were also produced upon UVPD, providing some illumination of tertiary and quaternary protein structural features.
