Oligomerization of nitrophorins
Analytical Biochemistry, 2006Rhodnius prolixus is a blood-sucking insect that uses a mixture of nitrophorin (NP) proteins to deliver nitric oxide (NO) from the insect saliva to the hosts via a ferric heme coordinated to the protein, causing vasodilatation and anticoagulation to support their feeding.

The PrP propensity to adopt different structures is tightly linked to transmissible spongiform encephalopathies (TSE) which include Creutzfeldt-Jakob disease (CJD), Gerstmann-Sträussler-Scjeinker (GSS) and Kuru syndrome. In most cases, TSE is associated with the accumulation in the brain of an abnormally folded protease-resistant protein, PrP Sc or ...

The controlled basic hydrolysis of tetrabutyl-1,3-dichlorodistannoxane under interfacial conditions was found to lead to α,ω-dichlorooligostannoxanes, Cl(SnBu2O)nSnBu2Cl, n being controlled by the molar ratio of base to distannoxane. These oligostannoxanes were identical with those prepared by other methods.

AbstractDie Reaktion von Natrium‐, Kalium‐ und Ammoniumsalzen der Di‐ und Triphosphorsäure mit Acetanhydrid führt bei Raumtemperatur primär zur Bildung von symmetrischen Diacetyldi‐ bzw. Diacetyltriphosphaten, die sich auf Grund der starken Hochfeldverschiebung der Endgruppen 31P‐NMR‐spektroskopisch eindeutig nachweisen lassen. Kalium‐ und das Ammonium‐

Abstract Three oligomeric arylstibonates [H5(p-ClC6H4Sb)16O36]3−, [H4(p-ClC6H4Sb)16O36]4−, and [Na2(p-ClC6H4Sb)12O24(OH)6(H2O)3]4− have been synthesized as tetra-n-butylammonium salts and structurally characterized. The Sb16C16O36 core of the [H5(p-ClC6H4Sb)16O36]3− and [H4(p-ClC6H4Sb)16O36]4− anions is made up from arrays of close ...

This chapter provides a foundation for further research into the relationship between dynamic oligomeric properties and functional diversity. The structural basis that underlies the conformational sub-states of the GAPDH oligomer is discussed. The issue of protein stability is given a thorough analysis, since it is well-established that the primary ...

AbstractHigh conversions of oligomeric silazanes that are not volatile at 200°C/0.1 mm are obtained when hexamethylcyclotrisilazane or octamethylcyclotetrasilazane is heated with a molar deficiency of dichlorodimethylsilane at 175°C. The oligomers, which show moderate solvolytic stability, contain disilazane, trisilylamine, and cyclodisilazane units ...
