PURPOSE: To produce a high-performance polyetherketone having amino groups bonded through alkyl groups by dissolving a polyetherketone in sulfuric acid, haloalkylating the polymer, and aminating the haloalkylation product in an amine compd. soln. ;CONSTITUTION: A polyetherketone of the formula is ...
SOLUTION: The objective molecular compound is obtained by using a phenol derivative of the formula (R1 and R5 are each H, a halogen, a 1-4C alkyl or the likes; R2 and R4 are each H, a 1-4C alkoxy, OH or the like, with the proviso that when one of R1 , R3 and R5 is a 1-...
superposition of the nucleotide structures reveals significant differences in the uracil moiety for UDP versus UDP-Gal/UDP-2F-Glc (specifically, the β-phosphate orientation differs significantly), as well as in

However, the biosynthetic mechanism of azoxy bond remains enigmatic. Here we report that the azoxy bond biosynthesis of azoxymycins is an enzymatic and non-enzymatic coupling cascade reaction. In the first step, nonheme diiron N-oxygenase AzoC catalyzes the oxidization of amine to its nitroso ...
Organic amine salt is an efficient sulfurization accelerator for copper oxide minerals. In fact, its underlying function mechanism is scarce. In this study, the evolution of sulfurized products of azurite under ethylenediamine (EDA) regulation and its response to the xanthate adsorption and surface ...

confirmed thatYpDHPS as well as other orthologs operate via a SN1 reaction mechanism, initiated by the binding of DHPP to the active site, elimination of pyrophosphate, leaving a carbocation form of the pterin (DHP+) that reacts with the weakly nucleophilicpABA amine group to form 7,8-DHP...
To maximize critical interactions between the benzonitrile fluorescent rotor and the protein upon ligand binding, the fluorophore was directly conjugated to the Lys-Urea-Glu scaffold at the ε-amine of lysine to yield Glu-490 (Supplementary Fig. 1). Additionally, we synthesized ODAP-490 and ODAP...
