Procedures by which protein structure and function are changed or created in vitro by altering existing or synthesizing new structural genes that direct the synthesis of proteins with sought-after properties. Such procedures may include the design of MOLECULAR MODELS of proteins using COMPUTER GRAPHICS or other molecular modeling techniques; site-specific mutagenesis (MUTAGENESIS, SITE-SPECIFIC) of existing genes; and DIRECTED MOLECULAR EVOLUTION techniques to create new genes.
Directed Molecular Evolution
The techniques used to produce molecules exhibiting properties that conform to the demands of the experimenter. These techniques combine methods of generating structural changes with methods of selection. They are also used to examine proposed mechanisms of evolution under in vitro selection conditions.
The characteristic 3-dimensional shape of a protein, including the secondary, supersecondary (motifs), tertiary (domains) and quaternary structure of the peptide chain. PROTEIN STRUCTURE, QUATERNARY describes the conformation assumed by multimeric proteins (aggregates of more than one polypeptide chain).
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Amino Acid Sequence
The internal fragments of precursor proteins (INternal proTEINS) that are autocatalytically removed by PROTEIN SPLICING. The flanking fragments (EXTEINS) are ligated forming mature proteins. The nucleic acid sequences coding for inteins are considered to be MOBILE GENETIC ELEMENTS. Inteins are composed of self-splicing domains and an endonuclease domain which plays a role in the spread of the intein's genomic sequence. Mini-inteins are composed of the self-splicing domains only.
A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.
Body of knowledge related to the use of organisms, cells or cell-derived constituents for the purpose of developing products which are technically, scientifically and clinically useful. Alteration of biologic function at the molecular level (i.e., GENETIC ENGINEERING) is a central focus; laboratory methods used include TRANSFECTION and CLONING technologies, sequence and structure analysis algorithms, computer databases, and gene and protein structure function analysis and prediction.
Protein Structure, Secondary
The excision of in-frame internal protein sequences (INTEINS) of a precursor protein, coupled with ligation of the flanking sequences (EXTEINS). Protein splicing is an autocatalytic reaction and results in the production of two proteins from a single primary translation product: the intein and the mature protein.
Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.
Protein Structure, Tertiary
The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.
Amino Acid Substitution
The naturally occurring or experimentally induced replacement of one or more AMINO ACIDS in a protein with another. If a functionally equivalent amino acid is substituted, the protein may retain wild-type activity. Substitution may also diminish, enhance, or eliminate protein function. Experimentally induced substitution is often used to study enzyme activities and binding site properties.
Cell Surface Display Techniques
A rigorously mathematical analysis of energy relationships (heat, work, temperature, and equilibrium). It describes systems whose states are determined by thermal parameters, such as temperature, in addition to mechanical and electromagnetic parameters. (From Hawley's Condensed Chemical Dictionary, 12th ed)
Recombinant Fusion Proteins
Hydroxymethyl and Formyl Transferases
The determination of the concentration of a given component in solution (the analyte) by addition of a liquid reagent of known strength (the titrant) until an equivalence point is reached (when the reactants are present in stoichiometric proportions). Often an indicator is added to make the equivalence point visible (e.g., a change in color).
The molecular designing of drugs for specific purposes (such as DNA-binding, enzyme inhibition, anti-cancer efficacy, etc.) based on knowledge of molecular properties such as activity of functional groups, molecular geometry, and electronic structure, and also on information cataloged on analogous molecules. Drug design is generally computer-assisted molecular modeling and does not include pharmacokinetics, dosage analysis, or drug administration analysis.
Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are linear polypeptides that are normally synthesized on RIBOSOMES.
The arrangement of two or more amino acid or base sequences from an organism or organisms in such a way as to align areas of the sequences sharing common properties. The degree of relatedness or homology between the sequences is predicted computationally or statistically based on weights assigned to the elements aligned between the sequences. This in turn can serve as a potential indicator of the genetic relatedness between the organisms.
Sequence Homology, Amino Acid
Nuclear Magnetic Resonance, Biomolecular
A basic enzyme that is present in saliva, tears, egg white, and many animal fluids. It functions as an antibacterial agent. The enzyme catalyzes the hydrolysis of 1,4-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in peptidoglycan and between N-acetyl-D-glucosamine residues in chitodextrin. EC 126.96.36.199.
Hydrophobic and Hydrophilic Interactions
A field of biology concerned with the development of techniques for the collection and manipulation of biological data, and the use of such data to make biological discoveries or predictions. This field encompasses all computational methods and theories for solving biological problems including manipulation of models and datasets.
Mixed Function Oxygenases
Widely distributed enzymes that carry out oxidation-reduction reactions in which one atom of the oxygen molecule is incorporated into the organic substrate; the other oxygen atom is reduced and combined with hydrogen ions to form water. They are also known as monooxygenases or hydroxylases. These reactions require two substrates as reductants for each of the two oxygen atoms. There are different classes of monooxygenases depending on the type of hydrogen-providing cosubstrate (COENZYMES) required in the mixed-function oxidation.
Protein Structure, Quaternary
A molecule that binds to another molecule, used especially to refer to a small molecule that binds specifically to a larger molecule, e.g., an antigen binding to an antibody, a hormone or neurotransmitter binding to a receptor, or a substrate or allosteric effector binding to an enzyme. Ligands are also molecules that donate or accept a pair of electrons to form a coordinate covalent bond with the central metal atom of a coordination complex. (From Dorland, 27th ed)
Magnetic Resonance Spectroscopy
DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.
Sequence Analysis, Protein
A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).
Tools or devices for generating products using the synthetic or chemical conversion capacity of a biological system. They can be classical fermentors, cell culture perfusion systems, or enzyme bioreactors. For production of proteins or enzymes, recombinant microorganisms such as bacteria, mammalian cells, or insect or plant cells are usually chosen.
Electrophoresis, Polyacrylamide Gel
A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
Guided Tissue Regeneration
Procedures for enhancing and directing tissue repair and renewal processes, such as BONE REGENERATION; NERVE REGENERATION; etc. They involve surgically implanting growth conducive tracks or conduits (TISSUE SCAFFOLDING) at the damaged site to stimulate and control the location of cell repopulation. The tracks or conduits are made from synthetic and/or natural materials and may include support cells and induction factors for CELL GROWTH PROCESSES; or CELL MIGRATION.
Amino Acid Motifs
Assembly requirements of PU.1-Pip (IRF-4) activator complexes: inhibiting function in vivo using fused dimers. (1/4007)Gene expression in higher eukaryotes appears to be regulated by specific combinations of transcription factors binding to regulatory sequences. The Ets factor PU.1 and the IRF protein Pip (IRF-4) represent a pair of interacting transcription factors implicated in regulating B cell-specific gene expression. Pip is recruited to its binding site on DNA by phosphorylated PU.1. PU.1-Pip interaction is shown to be template directed and involves two distinct protein-protein interaction surfaces: (i) the ets and IRF DNA-binding domains; and (ii) the phosphorylated PEST region of PU.1 and a lysine-requiring putative alpha-helix in Pip. Thus, a coordinated set of protein-protein and protein-DNA contacts are essential for PU.1-Pip ternary complex assembly. To analyze the function of these factors in vivo, we engineered chimeric repressors containing the ets and IRF DNA-binding domains connected by a flexible POU domain linker. When stably expressed, the wild-type fused dimer strongly repressed the expression of a rearranged immunoglobulin lambda gene, thereby establishing the functional importance of PU.1-Pip complexes in B cell gene expression. Comparative analysis of the wild-type dimer with a series of mutant dimers distinguished a gene regulated by PU.1 and Pip from one regulated by PU.1 alone. This strategy should prove generally useful in analyzing the function of interacting transcription factors in vivo, and for identifying novel genes regulated by such complexes. (+info)
Engineering a chimeric pyrroloquinoline quinone glucose dehydrogenase: improvement of EDTA tolerance, thermal stability and substrate specificity. (2/4007)An engineered Escherichia coli PQQ glucose dehydrogenase (PQQGDH) with improved enzymatic characteristics was constructed by substituting and combining the gene-encoding protein regions responsible for EDTA tolerance, thermal stability and substrate specificity. The protein region responsible for complete EDTA tolerance in Acinetobacter calcoaceticus, which is recognized as the indicator of high stability in co-factor binding, was elucidated. The region is located between 32 and 59% from the N-terminus of A. calcoaceticus PQQGDH(A27 region) and also corresponds to the same position from 32 to 59% from the N-terminus in E. coli PQQGDH, though E. coli PQQGDH is EDTA sensitive. We previously reported that the C-terminal 3% region of A. calcoaceticus (A3 region) played an important role in the increase of thermal stability, and that His775Asn substitution in E. coli PQQGDH resulted in an increase in the substrate specificity of E. coli PQQGDH towards glucose. Based on these findings, chimeric and/or mutated PQQGDHs, E97A3 H775N, E32A27E41 H782N, E32A27E38A3 and E32A27E38A3 H782N were constructed to investigate the compatibility of two protein regions and one amino acid substitution. His775 substitution to Asn corresponded to His782 substitution to Asn (H782N) in chimeric enzymes harbouring the A27 region. Since all the chimeric PQQGDHs harbouring the A27 region were EDTA tolerant, the A27 region was found to be compatible with the other region and substituted amino acid responsible for the improvement of enzymatic properties. The contribution of the A3 region to thermal stability complemented the decrease in the thermal stability due to the His775 or His782 substitution to Asn. E32A27E38A3 H782N, which harbours all the above mentioned three regions, showed improved EDTA tolerance, thermal stability and substrate specificity. These results suggested a strategy for the construction of a semi-artificial enzyme by substituting and combining the gene-encoding protein regions responsible for the improvement of enzyme characteristics. The characteristics of constructed chimeric PQQGDH are discussed based on the predicted model, beta-propeller structure. (+info)
Toward controlling gene expression at will: selection and design of zinc finger domains recognizing each of the 5'-GNN-3' DNA target sequences. (3/4007)We have taken a comprehensive approach to the generation of novel DNA binding zinc finger domains of defined specificity. Herein we describe the generation and characterization of a family of zinc finger domains developed for the recognition of each of the 16 possible 3-bp DNA binding sites having the sequence 5'-GNN-3'. Phage display libraries of zinc finger proteins were created and selected under conditions that favor enrichment of sequence-specific proteins. Zinc finger domains recognizing a number of sequences required refinement by site-directed mutagenesis that was guided by both phage selection data and structural information. In many cases, residues not expected to make base-specific contacts had effects on specificity. A number of these domains demonstrate exquisite specificity and discriminate between sequences that differ by a single base with >100-fold loss in affinity. We conclude that the three helical positions -1, 3, and 6 of a zinc finger domain are insufficient to allow for the fine specificity of the DNA binding domain to be predicted. These domains are functionally modular and may be recombined with one another to create polydactyl proteins capable of binding 18-bp sequences with subnanomolar affinity. The family of zinc finger domains described here is sufficient for the construction of 17 million novel proteins that bind the 5'-(GNN)6-3' family of DNA sequences. These materials and methods should allow for the rapid construction of novel gene switches and provide the basis for a universal system for gene control. (+info)
Re-design of Rhodobacter sphaeroides dimethyl sulfoxide reductase. Enhancement of adenosine N1-oxide reductase activity. (4/4007)The periplasmic DMSO reductase from Rhodobacter sphaeroides f. sp. denitrificans has been expressed in Escherichia coli BL21(DE3) cells in its mature form and with the R. sphaeroides or E. coli N-terminal signal sequence. Whereas the R. sphaeroides signal sequence prevents formation of active enzyme, addition of a 6x His-tag at the N terminus of the mature peptide maximizes production of active enzyme and allows for affinity purification. The recombinant protein contains 1.7-1.9 guanines and greater than 0.7 molybdenum atoms per molecule and has a DMSO reductase activity of 3.4-3.7 units/nmol molybdenum, compared with 3.7 units/nmol molybdenum for enzyme purified from R. sphaeroides. The recombinant enzyme differs from the native enzyme in its color and spectrum but is indistinguishable from the native protein after redox cycling with reduced methyl viologen and Me2SO. Substitution of Cys for the molybdenum-ligating Ser-147 produced a protein with DMSO reductase activity of 1.4-1.5 units/nmol molybdenum. The mutant protein differs from wild type in its color and absorption spectrum in both the oxidized and reduced states. This substitution leads to losses of 61-99% of activity toward five substrates, but the adenosine N1-oxide reductase activity increases by over 400%. (+info)
CD86 (B7-2) can function to drive MHC-restricted antigen-specific CTL responses in vivo. (5/4007)Activation of T cells requires both TCR-specific ligation by direct contact with peptide Ag-MHC complexes and coligation of the B7 family of ligands through CD28/CTLA-4 on the T cell surface. We recently reported that coadministration of CD86 cDNA along with DNA encoding HIV-1 Ags i.m. dramatically increased Ag-specific CTL responses. We investigated whether the bone marrow-derived professional APCs or muscle cells were responsible for the enhancement of CTL responses following CD86 coadministration. Accordingly, we analyzed CTL induction in bone marrow chimeras. These chimeras are capable of generating functional viral-specific CTLs against vaccinia virus and therefore represent a useful model system to study APC/T cell function in vivo. In vaccinated chimeras, we observed that only CD86 + Ag + MHC class I results in 1) detectable CTLs following in vitro restimulation, 2) detectable direct CTLs, 3) enhanced IFN-gamma production in an Ag-specific manner, and 4) dramatic tissue invasion of T cells. These results support that CD86 plays a central role in CTL induction in vivo, enabling non-bone marrow-derived cells to prime CTLs, a property previously associated solely with bone marrow-derived APCs.

Elimination of the immunogenicity of therapeutic antibodies. (6/4007)The immunogenicity of therapeutic Abs limits their long-term use. The processes of complementarity-determining region grafting, resurfacing, and hyperchimerization diminish mAb immunogenicity by reducing the number of foreign residues. However, this does not prevent anti-idiotypic and anti-allotypic responses following repeated administration of cell-binding Abs. Classical studies have demonstrated that monomeric human IgG is profoundly tolerogenic in a number of species. If cell-binding Abs could be converted into monomeric non-cell-binding tolerogens, then it should be possible to pretolerize patients to the therapeutic cell-binding form. We demonstrate that non-cell-binding minimal mutants of the anti-CD52 Ab CAMPATH-1H lose immunogenicity and can tolerize to the "wild-type" Ab in CD52-expressing transgenic mice. This finding could have utility in the long-term administration of therapeutic proteins to humans. (+info)
Combinatorial protein engineering by incremental truncation. (7/4007)We have developed a combinatorial approach, using incremental truncation libraries of overlapping N- and C-terminal gene fragments, that examines all possible bisection points within a given region of an enzyme that will allow the conversion of a monomeric enzyme into its functional heterodimer. This general method for enzyme bisection will have broad applications in the engineering of new catalytic functions through domain swapping and chemical synthesis of modified peptide fragments and in the study of enzyme evolution and protein folding. We have tested this methodology on Escherichia coli glycinamide ribonucleotide formyltransferase (PurN) and, by genetic selection, identified PurN heterodimers capable of glycinamide ribonucleotide transformylation. Two were chosen for physical characterization and were found to be comparable to the wild-type PurN monomer in terms of stability to denaturation, activity, and binding of substrate and cofactor. Sequence analysis of 18 randomly chosen, active PurN heterodimers revealed that the breakpoints primarily clustered in loops near the surface of the enzyme, that the breaks could result in the deletion of highly conserved residues and, most surprisingly, that the active site could be bisected.

Rational design of a scytalone dehydratase-like enzyme using a structurally homologous protein scaffold. (8/4007)The generation of enzymes to catalyze specific reactions is one of the more challenging problems facing protein engineers. Structural similarities between the enzyme scytalone dehydratase with nuclear transport factor 2 (NTF2) suggested the potential for NTF2 to be re-engineered into a scytalone dehydratase-like enzyme. We introduced four key catalytic residues into NTF2 to create a scytalone dehydratase-like active site. A C-terminal helix found in scytalone dehydratase but absent in NTF2 also was added. Mutant NTF2 proteins were tested for catalytic activity by using a spectroscopic assay. One of the engineered enzymes exhibited catalytic activity with minimal kcat and Km values of 0.125 min-1 and 800 microM, respectively. This level of catalytic activity represents minimally a 150-fold improvement in activity over the background rate for substrate dehydration and a dramatic step forward from the catalytically inert parent NTF2. This work represents one of the few examples of converting a protein scaffold into an enzyme, outside those arising from the induction of catalytic activity into antibodies. (+info)
British Library EThOS: Protein engineering studies of ovine BLG synthesised in yeast
β-lactoglobulin (BLG) is the major whey protein in ruminants and is found in the milk of a wide range of species. Extensive study of BLG over the years has led to the determination of the structure of the protein at 2.8AA and has revealed its ability to bind a variety of small hydrophobic molecules. However, the physiological function of BLG remains unknown despite its inclusion within the lipocalycin family on the grounds of genetic and tertiary structure comparisons as well as similarities in amino acid sequence. A protein engineering approach was adopted to study the residues involved in subunit interactions and ligand binding as well as the importance of Cys119 and 121 in determining the stability of the tertiary structure. The complete coding sequence for ovine BLG was obtained and a convenient site-directed mutagenesis system was set up. An expression system in the yeast Saccharomyces cerevisiae was developed in which ovine BLG was synthesised and secreted into the growth medium. ...

Improvement of food safety applied biosensors by protein engineering | National Agricultural Library
Determination of the histamine content is of paramount importance for the food industry as a parameter of the hygienic quality and freshness of food, as well as to prevent scombroid fish poisoning, an allergy-like food poisoning. At present, more sensitive and user-friendly methods for histamine monitoring are needed to early detect products and raw materials susceptible of becoming hazardous for consumers. BIOIMPROVE aims to develop an improved and highly sensitive portable biosensing device for the quantification of histamine in the lower concentration range (,5 mg/l). To reach this objective, an innovative and powerful semi-rational protein engineering strategy will be used to maximize the sensitivity of the currently available histamine enzyme-based biosensor. Rather than addressing this goal by the generation and screening of large libraries, a careful selection of the most promising mutational hotspots will be performed using the structural available information in tandem with advanced ...

Antibodies | Free Full-Text | Molecular Engineering of Therapeutic Cytokines
Over the past three decades, a large body of work has been directed at the development of therapeutic cytokines. Despite their central role in immune modulation, only a handful of cytokine therapeutics has achieved regulatory approval. One of the major challenges associated with the therapeutic use of cytokines relates to their short serum half-life and low bioavailability. High doses are required to overcome these problems, which often result in dose-limiting toxicities. Consequently, most cytokines require protein engineering approaches to reduce toxicity and increase half-life. For this purpose, PEGylation, fusion proteins, antibody complexes and mutagenesis have been utilized. Here, we summarize past, recent and emerging strategies in this area.
Structural and functional anatomy of the globular domain of complement protein C1q. - Immunology
C1q is the first subcomponent of the classical pathway of the complement system and a major connecting link between innate and acquired immunity. As a versatile charge pattern recognition molecule, C1q is capable of engaging a broad range of ligands via its heterotrimeric globular domain (gC1q) which is composed of the C-terminal regions of its A (ghA), B (ghB) and C (ghC) chains. Recent studies using recombinant forms of ghA, ghB and ghC have suggested that the gC1q domain has a modular organization and each chain can have differential ligand specificity. The crystal structure of the gC1q, molecular modeling and protein engineering studies have combined to illustrate how modular organization, charge distribution and the spatial orientation of the heterotrimeric assembly offer versatility of ligand recognition to C1q. Although the biochemical and structural studies have provided novel insights into the structure-function relationships within the gC1q domain, they have also raised many unexpected issues

Computational protein design: validation and possible relevance as a tool for homology searching and fold recognition. - Ecole...
BACKGROUND: Protein fold recognition usually relies on a statistical model of each fold; each model is constructed from an ensemble of natural sequences belonging to that fold. A complementary strategy may be to employ sequence ensembles produced by computational protein design. Designed sequences can be more diverse than natural sequences, possibly avoiding some limitations of experimental databases. METHODOLOGY/PRINCIPAL FINDINGS: WE EXPLORE THIS STRATEGY FOR FOUR SCOP FAMILIES: Small Kunitz-type inhibitors (SKIs), Interleukin-8 chemokines, PDZ domains, and large Caspase catalytic subunits, represented by 43 structures. An automated procedure is used to redesign the 43 proteins. We use the experimental backbones as fixed templates in the folded state and a molecular mechanics model to compute the interaction energies between sidechain and backbone groups. Calculations are done with the [email protected] volunteer computing platform. A heuristic algorithm is used to scan the sequence and conformational

Development of molecular recognition by rational and combinatorial engineering
Combinatorial protein engineering, taking advantage of large libraries of protein variants and powerful selection technology, is a useful strategy for developing affinity proteins for applications in biotechnology and medicine. In this thesis, two small affinity proteins have been subjected to combinatorial protein engineering to improve or redirect the binding. In two of the projects, a three-helix protein domain based on staphylococcal protein A has been used as scaffold to generate so called Affibody molecules capable of binding to key proteins related to two diseases common among elderly people.. In the first project, Affibody molecules were selected using phage display technology for binding to Ab-peptides, believed to play a crucial role in Alzheimers disease, in that they can oligomerize and contribute to the formation of neural plaques in the brain. The selected Affibody molecules were found to efficiently capture Ab from spiked human plasma when coupled to an affinity resin. The ...
Targeting Whats Inside: Exploring Antibody Therapeutics in Neurodegenerative Disease
As the population ages, the number of people with neurodegenerative diseases is expected to increase. Antibody therapeutics could be important in the fight against these diseases.
Enzyme engineering is a powerful technology now widely used in laboratories around the world. The goal is to obtain improved proteins that will serve as better biocatalysts, biosensors or as a tool to understand protein evolution, which is at the core of many societal problem, such as antibiotic resistance. Enzyme engineering entails the initial generation of libraries of mutants that will then be screened for improved properties (for example: better selectivity or specificity towards a substrate of interest, improved stability, etc). Obtaining good quality libraries is becoming routine thanks to the availability of molecular biology tools and computational simulations. The bottleneck of the experiment remains at the screening level. The bigger the generated library, the more stringent the requirement for the high-throughput screen ...

Feedback from thousands of designs could transform protein engineering | Technology news | latest news about information...
A large-scale study to test the actual stability of computationally designed proteins shows a way to take some of the guesswork out of protein engineering. Previously, scientists tested only a few tens of proteins, due to prohibitive costs of DNA. This new approach, which incorporates advances in DNA synthesis technology, efficiently checks thousands of mini-protein designs. The hope is that in the future a similar approach could test bigger, more complex, designed proteins ...

Richard Alfred Kammerer | LBR | Paul Scherrer Institut (PSI)
G-protein coupled receptors (GPCRs) are integral membrane proteins that share a common seven-transmembrane helix fold topology. They play fundamental roles in most physiological and many pathological processes. Currently, GPCRs are the target of ~30% of all medical drugs. As a result of the major drug discovery activities targeting GPCRs, there is a growing demand for high-resolution structures. Despite enormous efforts, however, progress in the structural characterization of GPCRs is rather slow. Primarily two methods have been developed for structural work on GPCRs: scanning alanine mutagenesis and the fusion protein engineering approach. However, both methods have substantial limitations, emphasizing that the development of new GPCR crystallization tools will be of fundamental importance in moving the field forward. Towards this aim, we developed a novel approach to facilitate the crystallization of GPCRs ...
Toxins | Free Full-Text | Multimodal Protein Constructs for Herbivore Insect Control
Transgenic plants expressing combinations of microbial or plant pesticidal proteins represent a promising tool for the efficient, durable control of herbivorous insects. In this review we describe current strategies devised for the heterologous co-expression of pesticidal proteins in planta, some of which have already shown usefulness in plant protection. Emphasis is placed on protein engineering strategies involving the insertion of single DNA constructs within the host plant genome. Multimodal fusion proteins integrating complementary pesticidal functions along a unique polypeptide are first considered, taking into account the structural constraints associated with protein or protein domain grafting to biologically active proteins. Strategies that allow for the co- or post-translational release of two or more pesticidal proteins are then considered, including polyprotein precursors releasing free proteins upon proteolytic cleavage, and multicistronic transcripts for the parallel translation of single
PLOS ONE: N-Terminal T4 Lysozyme Fusion Facilitates Crystallization of a G Protein Coupled Receptor
A highly crystallizable T4 lysozyme (T4L) was fused to the N-terminus of the β2 adrenergic receptor (β2AR), a G-protein coupled receptor (GPCR) for catecholamines. We demonstrate that the N-terminal fused T4L is sufficiently rigid relative to the receptor to facilitate crystallogenesis without thermostabilizing mutations or the use of a stabilizing antibody, G protein, or protein fused to the 3rd intracellular loop. This approach adds to the protein engineering strategies that enable crystallographic studies of GPCRs alone or in complex with a signaling partner.

Recent Comp Bio Pubs | Center for Computational Biology
Chemical biology has long sought to build protein switches for use in molecular diagnostics, imaging, and synthetic biology. The overarching challenge for any type of engineered protein switch is the ability to respond in a selective and predictable manner that caters to the specific environments and time scales needed for the application at hand. We previously described a general method to design switchable proteins, called chemical rescue of structure, that builds de novo allosteric control sites directly into a proteins functional domain. This approach entails first carving out a buried cavity in a protein via mutation, such that the proteins structure is disrupted and activity is lost. An exogenous ligand is subsequently added to substitute for the atoms that were removed by mutation, restoring the proteins structure and thus its activity. Here, we begin to ask what principles dictate such switches response to different activating ligands. Using a redesigned β-glycosidase enzyme as ...

The advent of economical gene synthesis is making it easier than ever to engineer completely new proteins. Computational protein design is a promising strategy to take advantage of our new found latitude. Previous computational protein design efforts have led to extraordinarily stable proteins (Tm above 99°C). However, the same algorithms also can lead to unfolded, aggregated, or destabilized proteins. It remains challenging to reliably design properties of interest (structure, stability, catalysis) into synthetic proteins. Furthermore, directed evolution raises the bar for computational design; it is often possible to optimize a protein of interest via screening libraries of random mutants thereof ...

Precise Design of Protein Structures
Author(s): Pan, Xingjie | Advisor(s): Kortemme, Tanja | Abstract: Proteins perform most of biological functions. The ultimate approach to understand protein functions is designing novel protein functions from scratch. The ability to design novel functional proteins would also be revolutionary for biology research, medicine and synthetic biology. Proteins function by placing specific chemical groups at precise 3-dimensional (3D) positions and orientations. Therefore, de novo functional protein design relies on precise control of protein 3D structures. In this thesis, I review the recent advances in de novo protein design (chapter 1). Then I describe two of my research projects that aim to extend the ability of computational methods to design precise protein 3D structures. In the first project (chapter 2), I developed a method termed loop-helix-loop unit combinatorial sampling (LUCS) that systematically samples geometries of protein secondary structures. I applied LUCS to designs de novo protein fold

Dr Ross Anderson - Biochemistry publications
A principal goal of synthetic biology is the de novo design or redesign of biomolecular components. In addition to revealing fundamentally important information regarding natural biomolecular engineering and biochemistry, functional building blocks will ultimately be provided for applications including the manufacture of valuable products and therapeutics. To fully realize this ambitious goal, the designed components must be biocompatible, working in concert with natural biochemical processes and pathways, while not adversely affecting cellular function. For example, de novo protein design has provided us with a wide repertoire of structures and functions, including those that can be assembled and function in vivo Here we discuss such biocompatible designs, as well as others that have the potential to become biocompatible, including non-protein molecules, and routes to achieving full biological integration..

Newcastle scientists develop future proof computer systems
It is very unusual for a university to be leading a project like this as its normally industry-led, so its a great honour for us to be working with some of the top names in European industry, he said. The industry partners put in 50 percent of their own money, which is a sure sign that they take this seriously.. From the start weve made it clear that were not going to carry out research that is not meeting industrys needs. This project will only be a success if we are able to create what they need and can use.. The scientists will be using formal engineering methods to test the fault tolerance of each system and refining these in an industrial setting to ensure they meet the needs of an increasingly technological society.. Its often crucial that you can rely on these systems, explained Computing Science Professor Cliff Jones, who began his career working for IBM in the 1970s and has spent many years developing formal engineering methods for industry.
