The O-GlcNAc modification involves the attachment of single beta-O-linked N-acetylglucosamine residues to serine and threonine residues of nucleocytoplasmic proteins. Interestingly, previous biochemical and structural studies have shown that O-GlcNAcase (OGA), the enzyme that removes O-GlcNAc from proteins, has an active site pocket that tolerates various N-acyl groups in addition to the N-acetyl group of GlcNAc. The remarkable sequence and structural conservation of residues comprising this pocket suggest functional importance. We hypothesized this pocket enables processing of metabolic variants of O-GlcNAc that could be formed due to inaccuracy within the metabolic machinery of the hexosamine biosynthetic pathway. In the accompanying paper (Bergfeld, A. K., Pearce, O. M., Diaz, S. L., Pham, T., and Varki, A. (2012) J. Biol. Chem. 287, 28865-28881), N-glycolylglucosamine (GlcNGc) was shown to be a catabolite of NeuNGc. Here, we show that the hexosamine salvage pathway can convert GlcNGc to UDP-GlcNGc, which is then used to modify proteins with O-GlcNGc. The kinetics of incorporation and removal of O-GlcNGc in cells occur in a dynamic manner on a time frame similar to that of O-GlcNAc. Enzymatic activity of O-GlcNAcase (OGA) toward a GlcNGc glycoside reveals OGA can process glycolyl-containing substrates fairly efficiently. A bacterial homolog (BtGH84) of OGA, from a human gut symbiont, also processes O-GlcNGc substrates, and the structure of this enzyme bound to a GlcNGc-derived species reveals the molecular basis for tolerance and binding of GlcNGc. Together, these results demonstrate that analogs of GlcNAc, such as GlcNGc, are metabolically viable species and that the conserved active site pocket of OGA likely evolved to enable processing of mis-incorporated analogs of O-GlcNAc and thereby prevent their accumulation. Such plasticity in carbohydrate processing enzymes may be a general feature arising from inaccuracy in hexosamine metabolic pathways.

Reactions of the new, closely related ligands 4,6-dichloro- N,N-di(pyridine-2-yl)-1,3,5-triazine-amine (Cldpat) and 6- chloro-N’-phenyl-N,N- di(pyridin-2-yl)-1,3,5-triazine-2,4-diamine (Cladpat) with iron(II) thiocyanate produced coordination compounds with drastically distinct magnetic properties. The compound trans-[Fe(Cldpat)2(NCS)2](H2O) (1) is a highspin complex from room temperature down to 5 K whereas the analogous compound trans-[Fe(Cladpat) 2 (NCS) 2] (2) exhibits spin-crossover (SCO) properties with T1/2 = 178K. Compounds 1 and 2 (both in its low-spin and high-spin states) have been structurally characterized by X-ray diffraction studies, which revealed identical metal coordination spheres. The SCO properties of 2 have been thoroughly investigated by temperature-dependent magnetic susceptibility measurements and differential scanning calorimetry (DSC), and a LIESST process with rapid relaxation of the trapped HS species has been observed. The equivalent coordination compound with selenocyanate anions, namely [Fe(Cladpat) 2 (NCSe) 2] (3) also displays SCO properties, although more gradual and with a lower T 1/2 value of 166 K.

Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter. 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, molecular formula is C14H20O10. In a Article，once mentioned of 10343-06-3, COA of Formula: C14H20O10

Novel inhibitors of Ras protein activation have been found, containing a bicyclic core derived from D-arabinose and benzyl and phenylhydroxylamine moieties. NMR studies (trNOE, saturation-transfer difference, STD) of the binding between these molecules and human p21 h-Ras are reported. A pharmacophore mapping indicates that both the benzyl and the phenylhydroxylamine moieties are essential for protein binding. Molecules lacking one of these groups were synthesized and tested to confirm this hypothesis, and no interaction with Ras in vitro, nor biological activity in mammalian cells was observed. Our studies led to the development of molecules that selectively inhibit Ras-dependent cellular growth in mammalian cells. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.

The generation of solar fuels by means of a photosynthetic apparatus strongly relies on the development of an efficient water oxidation catalyst (WOC). Cerium ammonium nitrate (CAN) is the most commonly used sacrificial oxidant to explore the potentiality of WOCs. It is usually assumed that CAN has the unique role to oxidatively energize WOCs, making them capable to offer a low-energy reaction pathway to transform H2O to O2. Herein, we show that CAN might have a much more relevant and direct role in WO, mainly related to the capture and liberation of O-O-containing molecular moieties.

Synthetic Route of 499-40-1, Chemical engineers work across a number of sectors, processes differ within each of these areas, are directly involved in the design, development, creation and manufacturing process of chemical products and materials. An article , which mentions 499-40-1, molecular formula is C12H22O11. The compound – (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal played an important role in people’s production and life.

Reaction of R(2-pyr)NH (where R = Me, Ph or 2-pyr) with ‘Bu2Mg’ in an ether-free environment yields the corresponding alkyl(amido)magnesium derivative [{R(2-pyr)NMgBu}n]. When polar solvent is added to these species only bis(amido)magnesium compounds separate from solution and not the expected solvated alkyl(amido) derivatives. Isolation of one such alkyl(amido) compound prior to reaction with donor solvent proves that the mixed anion species do indeed exist. However, when polar molecules are introduced a disproportionation reaction ensues, yielding the homoleptic compounds [{R2Mg ? (S)x}n] and [{(R2N)2Mg ? (S)x}n], where S is THF, TMEDA or PMDETA. Theoretical calculations likewise show that the disproportionation reaction of model compounds closely related to our systems is strongly exothermic. A 1H/13C NMR spectroscopic study was used to assign the nature of the bis(amido) species in solution. From these analyses it was possible to propose that the solvated bis(amido) derivatives assume a common structural motif, that of a monomer (n = 1) with a pseudo-octahedral magnesium center.
