Structural insights into the mechanism of formation of cellulosomes probed by small angle X-ray scattering. (1/23)

Exploring the mechanism by which the multiprotein complexes of cellulolytic organisms, the cellulosomes, attain their exceptional synergy is a challenge for biologists. We have studied the solution structures of the Clostridium cellulolyticum cellulosomal enzyme Cel48F in the free and complexed states with cohesins from Clostridium thermocellum and Clostridium cellulolyticum by small angle x-ray scattering in order to investigate the conformational events likely to occur upon complexation. The solution structure of the free cellulase indicates that the dockerin module is folded, whereas the linker connecting the catalytic module to the dockerin is extended and flexible. Remarkably, the docking of the different cohesins onto Cel48F leads to a pleating of the linker. The global structure determined here allowed modeling of the atomic structure of the C. cellulolyticum dockerin-cohesin interface, highlighting the local differences between both organisms responsible for the species specificity.  (+info)

Action of designer cellulosomes on homogeneous versus complex substrates: controlled incorporation of three distinct enzymes into a defined trifunctional scaffoldin. (2/23)

In recent work, we reported the self-assembly of a comprehensive set of defined "bifunctional" chimeric cellulosomes. Each complex contained the following: (i) a chimeric scaffoldin possessing a cellulose-binding module and two cohesins of divergent specificity and (ii) two cellulases, each bearing a dockerin complementary to one of the divergent cohesins. This approach allowed the controlled integration of desired enzymes into a multiprotein complex of predetermined stoichiometry and topology. The observed enhanced synergy on recalcitrant substrates by the bifunctional designer cellulosomes was ascribed to two major factors: substrate targeting and proximity of the two catalytic components. In the present work, the capacity of the previously described chimeric cellulosomes was amplified by developing a third divergent cohesin-dockerin device. The resultant trifunctional designer cellulosomes were assayed on homogeneous and complex substrates (microcrystalline cellulose and straw, respectively) and found to be considerably more active than the corresponding free enzyme or bifunctional systems. The results indicate that the synergy between two prominent cellulosomal enzymes (from the family-48 and -9 glycoside hydrolases) plays a crucial role during the degradation of cellulose by cellulosomes and that one dominant family-48 processive endoglucanase per complex is sufficient to achieve optimal levels of synergistic activity. Furthermore cooperation within a cellulosome chimera between cellulases and a hemicellulase from different microorganisms was achieved, leading to a trifunctional complex with enhanced activity on a complex substrate.  (+info)

Molecular cloning and transcriptional and expression analysis of engO, encoding a new noncellulosomal family 9 enzyme, from Clostridium cellulovorans. (3/23)

Clostridium cellulovorans produces a major noncellulosomal family 9 endoglucanase EngO. A genomic DNA fragment (40 kb) containing engO and neighboring genes was cloned. The nucleotide sequence contained reading frames for endoglucanase EngO, a putative response regulator, and a putative sensor histidine kinase protein. The engO gene consists of 2,172 bp and encodes a protein of 724 amino acids with a molecular weight of 79,474. Northern hybridizations revealed that the engO gene is transcribed as a monocistronic 2.6-kb mRNA. 5' RNA ligase-mediated rapid amplification of cDNA ends (RLM-RACE) PCR analysis indicated that the single transcriptional start site of engO was located 264 bp upstream from the first nucleotide of the translation initiation codon. Alignment of the engO promoter region provided evidence for highly conserved sequences that exhibited strong similarity to the sigma(A) consensus promoter sequences of gram-positive bacteria. EngO contains a typical N-terminal signal peptide of 28 amino acid residues, followed by a 149-amino-acid sequence which is homologous to the family 4-9 carbohydrate-binding domain. Downstream of this domain was an immunoglobulin-like domain of 89 amino acids. The C terminus contains a family 9 catalytic domain of glycosyl hydrolase. Mass spectrometry analysis of EngO was in agreement with that deduced from the nucleotide sequence. Expression of engO mRNA increased from early to middle exponential phase and decreased during the early stationary phase. EngO was highly active toward carboxymethyl cellulose but showed no activity towards xylan. It was optimally active at 40 to 50 degrees C and pH 5 to 6. The analysis of the products from the cellulose hydrolysis through thin-layer chromatography indicated its endoglucanase activity.  (+info)

Structural basis of cellulosome efficiency explored by small angle X-ray scattering. (4/23)

Cellulose, the main structural component of plant cell walls, is the most abundant carbohydrate polymer in nature. To break down plant cell walls, anaerobic microorganisms have evolved a large extracellular enzyme complex termed cellulosome. This megadalton catalytic machinery organizes an enzymatic assembly, tenaciously bound to a scaffolding protein via specialized intermodular "cohesin-dockerin" interactions that serve to enhance synergistic activity among the different catalytic subunits. Here, we report the solution structure properties of cellulosome-like assemblies analyzed by small angle x-ray scattering and molecular dynamics. The atomic models, generated by our strategy for the free chimeric scaffoldin and for binary and ternary complexes, reveal the existence of various conformations due to intrinsic structural flexibility with no, or only coincidental, inter-cohesin interactions. These results provide primary evidence concerning the mechanisms by which these protein assemblies attain their remarkable synergy. The data suggest that the motional freedom of the scaffoldin allows precise positioning of the complexed enzymes according to the topography of the substrate, whereas short-scale motions permitted by residual flexibility of the enzyme linkers allow "fine-tuning" of individual catalytic domains.  (+info)

Transcriptional analysis of the cip-cel gene cluster from Clostridium cellulolyticum. (5/23)

Twelve genes encoding key components of Clostridium cellulolyticum cellulosomes are clustered. Among them, the first, second, and fifth genes encode the assembly factor CipC and the two major cellulases Cel48F and Cel9E, respectively. Cellulolytic clones were selected from the noncellulolytic cipC insertional mutant trans-complemented with a cipC expression vector, in which one homologous recombination event between the 3' end of the chromosomal cipC gene and the plasmidic cipC gene has restored the cluster continuity. The absence of the enzymes encoded by the cluster in the cipC mutant was thus only due to a strong polar effect, indicating that all genes were transcriptionally linked. Two large transcripts were detected in cellulose-grown cells by Northern hybridization: a 14-kb messenger which carries the cipC-cel48F-cel8C-cel9G-cel9E coding sequences and, in a smaller amount, a 12-kb messenger which carries the genes located in the 3' part of the cluster. Four smaller transcripts were found in large amounts: a cipC-cel48F bicistronic one and three monocistronic ones, cipC, cel48F, and cel9E. The cipC-cel48F and cel48F messengers were shown to be stable. Analysis by reverse transcription-PCR suggested transcriptional linkage of all of the open reading frames. The production of a primary very large transcript covering the entire cluster was hypothesized. Primer extension analysis has identified two putative transcriptional start sites located 638/637 and 194 nucleotides upstream of the cipC translational start. The processing of the primary transcript would lead to the production of several secondary messengers displaying different stabilities, contributing to fine tuning of expression of individual genes of the operon.  (+info)

Enzyme diversity of the cellulolytic system produced by Clostridium cellulolyticum explored by two-dimensional analysis: identification of seven genes encoding new dockerin-containing proteins. (6/23)

The enzyme diversity of the cellulolytic system produced by Clostridium cellulolyticum grown on crystalline cellulose as a sole carbon and energy source was explored by two-dimensional electrophoresis. The cellulolytic system of C. cellulolyticum is composed of at least 30 dockerin-containing proteins (designated cellulosomal proteins) and 30 noncellulosomal components. Most of the known cellulosomal proteins, including CipC, Cel48F, Cel8C, Cel9G, Cel9E, Man5K, Cel9M, and Cel5A, were identified by using two-dimensional Western blot analysis with specific antibodies, whereas Cel5N, Cel9J, and Cel44O were identified by using N-terminal sequencing. Unknown enzymes having carboxymethyl cellulase or xylanase activities were detected by zymogram analysis of two-dimensional gels. Some of these enzymes were identified by N-terminal sequencing as homologs of proteins listed in the NCBI database. Using Trap-Dock PCR and DNA walking, seven genes encoding new dockerin-containing proteins were cloned and sequenced. Some of these genes are clustered. Enzymes encoded by these genes belong to glycoside hydrolase families GH2, GH9, GH10, GH26, GH27, and GH59. Except for members of family GH9, which contains only cellulases, the new modular glycoside hydrolases discovered in this work could be involved in the degradation of different hemicellulosic substrates, such as xylan or galactomannan.  (+info)

Incorporation of fungal cellulases in bacterial minicellulosomes yields viable, synergistically acting cellulolytic complexes. (7/23)

Artificial designer minicellulosomes comprise a chimeric scaffoldin that displays an optional cellulose-binding module (CBM) and bacterial cohesins from divergent species which bind strongly to enzymes engineered to bear complementary dockerins. Incorporation of cellulosomal cellulases from Clostridium cellulolyticum into minicellulosomes leads to artificial complexes with enhanced activity on crystalline cellulose, due to enzyme proximity and substrate targeting induced by the scaffoldin-borne CBM. In the present study, a bacterial dockerin was appended to the family 6 fungal cellulase Cel6A, produced by Neocallimastix patriciarum, for subsequent incorporation into minicellulosomes in combination with various cellulosomal cellulases from C. cellulolyticum. The binding of the fungal Cel6A with a bacterial family 5 endoglucanase onto chimeric miniscaffoldins had no impact on their activity toward crystalline cellulose. Replacement of the bacterial family 5 enzyme with homologous endoglucanase Cel5D from N. patriciarum bearing a clostridial dockerin gave similar results. In contrast, enzyme pairs comprising the fungal Cel6A and bacterial family 9 endoglucanases were substantially stimulated (up to 2.6-fold) by complexation on chimeric scaffoldins, compared to the free-enzyme system. Incorporation of enzyme pairs including Cel6A and a processive bacterial cellulase generally induced lower stimulation levels. Enhanced activity on crystalline cellulose appeared to result from either proximity or CBM effects alone but never from both simultaneously, unlike minicellulosomes composed exclusively of bacterial cellulases. The present study is the first demonstration that viable designer minicellulosomes can be produced that include (i) free (noncellulosomal) enzymes, (ii) fungal enzymes combined with bacterial enzymes, and (iii) a type (family 6) of cellulase never known to occur in natural cellulosomes.  (+info)

Evolution of acetoclastic methanogenesis in Methanosarcina via horizontal gene transfer from cellulolytic Clostridia. (8/23)

Phylogenetic analysis confirmed that two genes required for acetoclastic methanogenesis, ackA and pta, were horizontally transferred to the ancestor of Methanosarcina from a derived cellulolytic organism in the class Clostridia. This event likely occurred within the last 475 million years, causing profound changes in planetary methane biogeochemistry.  (+info)

Transcription and expression regulation of some individual cel genes (cel5A, cel5I, cel5D and cel44O) of Clostridium cellulolyticum were investigated. Unlike the cip-cel operon, these genes are transcribed as monocistronic units of transcription, except cel5D. The location of the transcription initiation sites was determined using RT-PCR and the mRNA 5′-end extremities were detected using primer extension experiments. Similarly to the cip-cel operon, cel5A and cel5I expressions are regulated by a carbon catabolite repression mechanism, whereas cel44O and cel5D expressions do not seem to be submitted to this regulation. The role of the putative transcriptional regulator GlyR2 in the regulation of cel5D expression was investigated. The recombinant protein GlyR2 was produced and was shown to bind in vitro to the cel5D and glyR2 promoter regions, suggesting that besides regulating its own expression, GlyR2 may regulate cel5D expression. To test this hypothesis in vivo, an insertional glyR2 mutant ...
1G9J: Structures of mutants of cellulase Cel48F of Clostridium cellulolyticum in complex with long hemithiocellooligosaccharides give rise to a new view of the substrate pathway during processive action
The rise in oil prices and environmental concerns has heightened interest in the microbial production of fuels and chemicals from sugar feedstocks produced from renewable biomass. Branched higher alcohols are both representative promising next-generation biofuels and building blocks for producing a variety of chemicals [1,2]. In particular, isobutanol can be used as a fuel, fuel additive, and a commodity chemical, and thus is an important biorefinery target alcohol. Furthermore, isobutanol has attractive properties, including lower toxicity and higher octane value than its straight-chain counterpart [3].. Metabolically engineered microbial strains for producing isobutanol have been developed by introducing parts of the Ehrlich pathway into bacterial hosts such as Escherichia coli, Corynebacterium glutamicum, Clostridium cellulolyticum, and Bacillus subtilis [3-8]. In these recombinant strains, an intermediate of valine biosynthesis, 2-ketoisovalerate, is converted into isobutanol through ...

In this study, the evolution of cellulose degradation was a defining event in the history of life. Without efficient decomposition and recycling, dead plant biomass would quickly accumulate and become inaccessible to terrestrial food webs and the global carbon cycle. On land, the primary drivers of plant biomass deconstruction are fungi and bacteria in the soil or associated with herbivorous eukaryotes. While the ecological importance of plant-decomposing microbes is well established, little is known about the distribution or evolution of cellulolytic activity in any bacterial genus. Here we show that in Streptomyces, a genus of Actinobacteria abundant in soil and symbiotic niches, the ability to rapidly degrade cellulose is largely restricted to two clades of host-associated strains and is not a conserved characteristic of the Streptomyces genus or host-associated strains. Our comparative genomics identify that while plant biomass degrading genes (CAZy) are widespread in Streptomyces, key ...
Cellulosomes known as the proficient nanomachine in nature are cell bound multi-enzyme complexes that break down cellulose and hemicelluloses. They are very important in the process of carbon turnover. The cellulosome complexes require highly ordered proteins (the interactions between cohesions and dockerins) to assembly cellulases and hemicellulases into a scaffold structure. The protein interactions between cohesion and dockerin play an important role in cellulosome assembly and the attachment of cellulosome to the surface of cells while remaining flexible to provide a stable catalytic synergy.. One function of cellulosomes is breaking down plants structural polysaccharides. It is hypothesize that the constraints of the cellulosomes system created by bacteria and fungi caused the deconstruction of plant cell wall to become more and more efficient. The splicing of the plant-cell wall involves the addition of enzymes on to a macromolecule complex will increase the effectiveness of the ...

The interaction between cellulase enzymes and their substrates is of central importance to several technological and scientific challenges. Here we report that the binding of cellulose binding modules (CBM) from Trichoderma reesei cellulases Cel6A and Cel7A show a major difference in how they interact with substrates originating from wood compared to bacterial cellulose. We found that the CBM from TrCel7A recognizes the two substrates differently and as a consequence shows an unexpected way of binding. We show that the substrate has a large impact on the exchange rate of the studied CBM, and moreover, CBM-TrCel7A seems to have an additional mode of binding on wood derived cellulose but not on cellulose originating from bacterial source. This mode is not seen in double CBM (DCBM) constructs comprising both CBM-TrCel7A and CBM-TrCel6A. The linker length of DCBMs affects the binding properties, and slows down the exchange rates of the proteins and thus, can be used to analyze the differences ...

Separation unit operations make up a critical portion of biologics downstream processes. Complexity inherently associated with biologics manufacture such as product heterogeneity and host impurities presents process challenges not typically encountered in small-molecule separations. With bioreactor titers increasing steadily over the last several years, production cost and operational pressures are shifting further to downstream. In addition, biological metabolites are still produced in relatively low amounts. The development of cost- and time-effective bioseparation and concentration unit ops is thus key to efficient downstream processes. This session will focus on highlighting the latest advances in bioseparations and downstream processing, aimed at cost reduction, improved efficiency, and shortend development time. Topics to be covered include, but are not limited to: Centrifugation; Crystallization, evaporation, and precipitation; Membrane-based separations; Adsorption and ion exchange; ...

Typical problem areas in footwear are under the heel and forefoot, and at the side of the heel. An oval patch can be applied to overlap the side of the heel counter and the insole as seen is the photo. I often use a rectangle or large oval under the ball of the foot or an oval under the heel - applied directly to the insole. The patches are useful over stitching or seams in footwear that are rubbing the wearer. If necessary, a patch can be cut to shape for where it will be applied.. The patches will reduce shear and friction; provide relief from hot spot and blister pain, and can be used in any type of insole or orthotic and footwear, from sandals to running shoes, and any type of hiking or ski boot.. I like ENGO patches because they work. The patch is thin and does not alter the fit of the shoe. When properly applied to dry footwear, they stick.. Rebecca Rushton, a podiatrist in Australia, strongly recommends ENGO Patches. She discovered the patches after getting blisters herself and now ...
