Synthesis of a Hexameric Magnesium 4-pyridyl Complex with Cyclohexane-like Ring Structure via Reductive C-N Activation.

ABSTRACT: The reaction of [{(Arnacnac)Mg}2] (Arnacnac = HC{MeC(NAr)}2, Ar = 2,6-diisopropylphenyl, Dip, or 2,6-diethylphenyl, Dep) with 4-dimethylaminopyridine (DMAP) at elevated temperatures afforded the hexameric magnesium 4-pyridyl complex [{(Arnacnac)Mg(4-C5H4N)}6] via reductive cleavage of the DMAP C-N bond. The title compound contains a large s-block organometallic cyclohexane-like ring structure comprising tetrahedral (Arnacnac)Mg nodes and linked by linear 4-pyridyl bridging ligands, and the structure is compared with other ring systems. [(Dipnacnac)Mg(DMAP)(NMe2)] was structurally characterised as a by-product.

Hexameric ring structure of the full-length archaeal MCM protein complex.

Project description:In eukaryotes, a family of six homologous minichromosome maintenance (MCM) proteins has a key function in ensuring that DNA replication occurs only once before cell division. Whereas all eukaryotes have six paralogues, in some Archaea a single protein forms a homomeric assembly. The complex is likely to function as a helicase during DNA replication. We have used electron microscopy to obtain a three-dimensional reconstruction of the full-length MCM from Methanobacterium thermoautotrophicum. Six monomers are arranged around a sixfold axis, generating a ring-shaped molecule with a large central cavity and lateral holes. The channel running through the molecule can easily accommodate double-stranded DNA. The crystal structure of the amino-terminal fragment of MCM and a model for the AAA+ hexamer have been docked into the map, whereas additional electron density suggests that the carboxy-terminal domain is located at the interface between the two domains. The structure suggests that the MCM complex is likely to act in a different manner to traditional hexameric helicases and is likely to bear more similarity to the SV40 large T antigen or to double-stranded DNA translocases.

A Salmonella type three secretion effector/chaperone complex adopts a hexameric ring-like structure.

Project description:Many bacterial pathogens use type three secretion systems (T3SS) to inject virulence factors, named effectors, directly into the cytoplasm of target eukaryotic cells. Most of the T3SS components are conserved among plant and animal pathogens, suggesting a common mechanism of recognition and secretion of effectors. However, no common motif has yet been identified for effectors allowing T3SS recognition. In this work, we performed a biochemical and structural characterization of the Salmonella SopB/SigE chaperone/effector complex by small-angle X-ray scattering (SAXS). Our results showed that the SopB/SigE complex is assembled in dynamic homohexameric-ring-shaped structures with an internal tunnel. In this ring, the chaperone maintains a disordered N-terminal end of SopB molecules, in a good position to be reached and processed by the T3SS. This ring dimensionally fits the ring-organized molecules of the injectisome, including ATPase hexameric rings; this organization suggests that this structural feature is important for ATPase recognition by T3SS. Our work constitutes the first evidence of the oligomerization of an effector, analogous to the organization of the secretion machinery, obtained in solution. As effectors share neither sequence nor structural identity, the quaternary oligomeric structure could constitute a strategy evolved to promote the specificity and efficiency of T3SS recognition.

Hexameric ring structure of human MCM10 DNA replication factor.

Project description:The DNA replication factor minichromosome maintenance 10 (MCM10) is a conserved, abundant nuclear protein crucial for origin firing. During the transition from pre-replicative complexes to pre-initiation complexes, MCM10 recruitment to replication origins is required to provide a physical link between the MCM2-7 complex DNA helicase and DNA polymerases. Here, we report the molecular structure of human MCM10 as determined by electron microscopy and single-particle analysis. The MCM10 molecule is a ring-shaped hexamer with large central and smaller lateral channels and a system of inner chambers. This structure, together with biochemical data, suggests that this important protein uses its architecture to provide a docking module for assembly of the molecular machinery required for eukaryotic DNA replication.

Hexameric structure of the ATPase motor subunit of magnesium chelatase in chlorophyll biosynthesis.

Project description:Magnesium chelatase (MgCh) is a heterotrimeric enzyme complex, composed of two AAA+ family subunits that can assembly into a double ring structure and a large catalytic subunit. The small AAA+ subunit has ATPase activity and can self-oligomerize into a ring structure, while the other AAA+ subunit lacks independent ATPase activity. Previous structural studies of the ATPase motor subunit of MgCh from a bacteriochlorophyll-synthesizing bacterium have identified a unique ATPase clade, but the model of oligomeric assembly is unclear. Here we present the hexameric structure of the MgCh ATPase motor subunit from the chlorophyll-synthesizing cyanobacterium Synechocystis sp. PCC 6803. This structure reveals details of how the hexameric ring is assembled, and thus provides a basis for further studying the heterotrimeric complex.

Cryo-EM structure of human hexameric MCM2-7 complex.

Project description:The central step in the initiation of eukaryotic DNA replication is the loading of the minichromosome maintenance 2-7 (MCM2-7) complex, the core of the replicative DNA helicase, onto chromatin at replication origin. Here, we reported the cryo-EM structure of endogenous human single hexameric MCM2-7 complex with a resolution at 4.4 Å, typically an open-ring hexamer with a gap between Mcm2 and Mcm5. Strikingly, further analysis revealed that human MCM2-7 can self-associate to form a loose double hexamer which potentially implies a novel mechanism underlying the MCM2-7 loading in eukaryote. The high-resolution cryo-EM structure of human MCM2-7 is critical for understanding the molecular mechanisms governing human DNA replication, especially the MCM2-7 chromatin loading and pre-replicative complex assembly.

The structure of a complex of hexameric insulin and 4'-hydroxyacetanilide.

Project description:X-ray crystallographic studies have been carried out on human insulin crystals grown in the presence of 4'-hydroxyacetanilide (Tylenol) and show that this nontoxic phenolic derivative can induce the T-->R transition, producing a T3R3 hexamer. Two different crystals, grown under different conditions, are rhombohedral, space group R3, with cell constants a = 81.11, c = 37.97 and a = 80.88, c = 37.60 A. The T3R3 hexamer is symmetric, resulting from the presence of a crystallographic threefold axis, and the asymmetric unit consists of a TR dimer. Data to a resolution of 1.9 A were measured on a crystal from each of the two crystallizations and the structures have been refined to residuals of 0.168 and 0.173. The guest molecule is bound by the R-state monomer through the formation of two hydrogen bonds from the hydroxy group of Tylenol to the carbonyl oxygen and the nitrogen of A6 Cys and A11 Cys, respectively. Due to steric constraints of the phenolic binding site, the acetamide group of Tylenol is rotated approximately 50 degrees out of the plane of the phenyl group and the methyl group is cis; no hydrogen bonds exist between the acetamide group and the hexamer. Although the zinc ion, which is bound to the R-state trimer, has tetrahedral coordination in both structures, the T-state zinc is observed to have octahedral coordination in one structure but tetrahedral coordination in the other. The side chain of A10 Ile in the R-state monomer adopts a high-energy conformation as a result of close contact to a residue in an adjacent dimer and may explain in part the differences between therapeutic preparations of beef insulin, for which A10 is a Val residue, and human insulin.

Synthesis and crystal structure of a PdII complex of ortho-xylylenebis(pyridyl-triazole).

Project description:A tetra-dentate ligand, namely, ortho-xylylenebis(pyridyl-triazole), o-xpt, was synthesized using the 'click' method and complexed with Pd(BF4)2. In the title com-plex, bis-{μ-1,1'-(o-xylylene)bis-[4-(pyridin-2-yl)triazole]-κN 3:N 3'}dipalladi-um(II) tetra-kis-(tetrafluoridoborate)-di-methyl-formamide-diethyl ether (1/2/1), as the BF4 salt, and including di-methyl-formamide and diethyl ether solvent mol-ecules, with stoichiometry [Pd2(C22H18N8)2](BF4)4·2C3H7NO·C4H10O, the Pd complex and the disordered diethyl ether mol-ecule lie on inversion centers. The ligand coordinates to the PdII centers with square-planar geometry, forming a dimeric macrocycle. The Pd⋯Pd separation in the complex [Pd2(o-xpt)2]4+ cation is 3.6184 (4) Å. In the crystal, the complex mol-ecules are stacked along the b axis, with π-π inter-actions between the pyridyl-triazole ligands of two mol-ecules.

Synthesis, Structure, and Reactivity of Magnesium Pentalenides.

Project description:The first magnesium pentalenide complexes have been synthesized via deprotonative metalation of 1,3,4,6-tetraphenyldihydropentalene (Ph4PnH2) with magnesium alkyls. Both the nature of the metalating agent and the reaction solvent influenced the structure of the resulting complexes, and an equilibrium between Mg[Ph4Pn] and [nBuMg]2[Ph4Pn] was found to exist and investigated by NMR, XRD, and UV-vis spectroscopic techniques. Studies on the reactivity of Mg[Ph4Pn] with water, methyl iodide, and trimethylsilylchloride revealed that the [Ph4Pn]2- unit undergoes electrophilic addition at 1,5-positions instead of 1,4-positions known for the unsubstituted pentalenide, Pn2-, highlighting the electronic influence of the four aryl substituents on the pentalenide core. The ratio of syn/anti addition was found to be dependent on the size of the incoming electrophile, with methylation yielding a 60:40 mixture, while silylation yielded exclusively the anti-isomer.

Structure of isochorismate synthase in complex with magnesium.

Project description:The electron carrier menaquinone is one of many important bacterial metabolites that are derived from the key intermediate chorismic acid. MenF, the first enzyme in the menaquinone pathway, catalyzes the isomerization of chorismate to isochorismate. Here, an improved structure of MenF in a new crystal form is presented. The structure, solved at 2.0 angstroms resolution in complex with magnesium, reveals a well defined closed active site. Existing evidence suggests that the mechanism of the reaction catalyzed by MenF involves nucleophilic attack of a water molecule on the chorismate ring. The structure reveals a well defined water molecule located in an appropriate position for activation by Lys190 and attack on the substrate.
