Glycoside cleavage by a new mechanism in unsaturated glucuronyl hydrolases

Unsaturated glucuronyl hydrolases (UGLs) from GH family 88 of the CAZy classification system cleave a terminal unsaturated sugar from the oligosaccharide products released by extracellular bacterial polysaccharide lyases. This pathway, which is involved in extracellular bacterial infection, has no equivalent in mammals. A novel mechanism for UGL has previously been proposed in which the enzyme catalyzes hydration of a vinyl ether group in the substrate, with subsequent rearrangements resulting in glycosidic bond cleavage. However, clear evidence for this mechanism has been lacking. In this study, analysis of the products of UGL-catalyzed reactions in water, deuterium oxide, and dilute methanol in water, in conjunction with the demonstration that UGL rapidly cleaves thioglycosides and glycosides of inverted anomeric configuration (substrates that are resistant to hydrolysis by classical glycosidases), provides strong support for this new mechanism. A hydration-initiated process is further supported by the observed UGL-catalyzed hydration of a C-glycoside substrate analogue. Finally, the observation of a small beta-secondary kinetic isotope effect suggests a transition state with oxocarbenium ion character, in which the hydrogen at carbon 4 adopts an axial geometry. Taken together, these observations validate the novel vinyl ether hydration mechanism and are inconsistent with either inverting or retaining direct hydrolase mechanisms at carbon 1.

A new alternating ferro- and antiferromagnetic, one-dimensional manganese(II) azide complex, [Mn(dpa)(N3)2] – Crystal structure and spectroscopic and magnetic properties

The synthesis, crystal structure, and spectroscopic and magnetic properties of a new alternating ferro- and antiferromagnetic, one-dimensional manganese(II) azide complex, [Mn(dpa)(N3)2] (where dpa is the 2,2?-dipyridylamine ligand), are reported. The compound’s crystal structure has been resolved at room temperature. The complex crystallizes in the monoclinic P21/c space group, with a = 7.089(2), b = 19.090(4), and c = 9.682(4) A, beta = 104.61(2) , and Z = 4. The structure consists of neutral chains in which each MnII cation is alternatively bridged by two end-on and two end-to-end azido bridges. The octahedral coordination of the metallic cation is completed by two dpa ligand nitrogen atoms. Reflectance measurements confirm the hexacoordination of the MnII ions in the complex. The ESR spectra at room temperature and at 4.2 K are isotropic, with a mean g-value of 2.010(1). Magnetic data were analyzed on the basis of an alternating ferro- and antiferromagnetic Heisenberg chain of MnII ions. The J-exchange parameters found are 64.3 and -75,7 K. A spin canting phenomenon has been observed in this compound, with a remnant magnetization which vanishes above 15 K. Magnetostructural correlations in manganese(II) systems of alternating magnetic sign are discussed.

Triruthenium and triosmium carbonyl cluster complexes containing deprotonated di(2-pyridyl)amine in unusual coordination modes

The synthesis of the first trinuclear carbonyl clusters containing ligands derived from di(2-pyridyl)amine (Hdpa) has been achieved. Treatment of [Ru3-(CO)12] or [Ru3(CO)10(MeCN)2] with di(2-pyridyl)amine (Hdpa) gives the cluster complex [Ru3(mu-H)(mu-eta3-dpa-C,N,N)(CO)9] (1). The dpa ligand in this compound chelates a Ru atom through both pyridinic nitrogens while attached to another Ru atom through the C atom of a metalated pyridine ring, keeping the amino NH fragment uncoordinated. Curiously, the osmium compounds [Os3(mu-H)(mu-eta2-dpa-N,N)(CO)10] (2) and [Os3(mu-H)(mu3-eta2-dpa-N,N)(CO)9 ] (3), which have been stepwise prepared from [Os3(CO)10(MeCN)2] and Hdpa, contain edge-bridging (2) and face-capping (3) N-deprotonated dpa ligands coordinated through the N atom of a pyridine ring and the N atom of the original amino fragment.

Self-Assembled Supramolecular Polyoxometalate Hybrid Architecture as a Multifunctional Oxidation Catalyst

Polyoxometalates (POMs) are widely applied as tuneable and versatile catalysts for a variety of oxidation reactions in an aqueous/organic two-phase system. However, the practical applications of POMs-based biphasic catalysis are hampered by low space-time yields and mass-transport limitation between two layers due to extremely low solubility of the organic reactants in the aqueous phase. Here, we first introduced beta-cyclodextrin (beta-CD) as an inverse phase transfer agent and a supramolecular nanoreactor to construct a supramolecular POM inorganic-organic hybrid framework (KCl4)Na7[(beta-CD)3(SiW12O40)]¡¤9H2O {3CD@SiW12} for various oxidation catalyses. In contrast to free CD, Keggin [SiW12O40]4- catalysts, and their mixture, the {3CD@SiW12} catalyst, efficiently catalyze oxidation reactions of alcohol, alkene, and thiophene. A comprehensive strategy of experimental, crystallographic, and density functional theory (DFT) calculations elucidates that the catalytic pathway involved three combined aspects of supramolecular recognition, phase transfer property, and POM catalysis. The strategic combination of supramolecular characteristic and POM-based catalysts to fabricate supramolecular POM hybrid materials opens up new economic and green tuning options, thus paving the way to informed catalyst design.
