surface hydroxyl groupozone decompositionhydroxyl radicalheavy oil produced water纬-Al2O3 was incorporated with SiO2 and used as carrier to support Ni and Cu oxides for catalytic ozonation of heavy oil produced water. The change of catalytic activity was in accordance with that of surface hydroxyl ...
In this case, T interacts similarly to aliphatic amino acids, which also have a methyl group at the end of their side chains. Another joker is Y, which belongs to the set of large aromatic/hydrophobic amino acids. Its hydroxyl group at the end of the side chain enables Y to interact ...
When amino acid sequences fold into a three-dimensional structure of strands, one amino acid R group will then project to the interior of the protein and the adjacent R group will project to the outside (to the water environment). β strands of proteins may be arranged adjacent to each ...
Thus, the ethoxycarbonyl group proved to serve as a versatile protecting group for not only H–P(O) but also HO–P(O) and hydroxyl groups of sugars.doi:10.1002/chin.198218336Sekine,MitsuoMori,HiroyukiHata,TsujiakiWILEY‐VCH Verlag GmbHCheminform...
constituted by patch residues. In the glucosylated motif (C1XaSXbP/AC2), residues Xband C2form three hydrogen bonds with Gln240 of loop 1 and Ala172 of loop 2 in the POGLUT1–EGF complex, whereas the hydroxyl group of the serine residue forms the fourth hydrogen bond with Asp133, the ...
Double-stranded RNA-specific endoribonuclease that generates products with two nucleotide 3′ overhangs, a 5′ phosphate and a 3′ hydroxyl group. dsRNA-binding protein Proteins containing double-stranded RNA-binding domains, which are ∼70 amino acid motifs that bind to RNA helices via their 2...
Sulfate polysaccharide is a kind of carbohydrate with sulfate groups on hydroxyl group, including various polysaccharides extracted from plants, heparin and chondroitin sulfate in animals, sulfate derivative of natural polysaccharides. Sulfate polysaccharide and its derivatives have many important biological ...
They are covalently attached to PG by a phosphodiester linkage to the C6-hydroxyl of MurNAc, via a linkage unit usually consisting of a disaccharide, N-acetylmannosaminyl-β(1-4)-N-acetylglucosamine, and a Gro-P unit (Figure 3). The typical LTA structure consists of a poly(Gro-P) chain...
as an intermediate8. In the final stages of the biosynthesis, the C-24 hydroxyl group is oxidized to a ketone and the C-7 acetyl group is cleaved, yielding lankacidin C, with the relative timing of these two transformations also remaining to be established (Fig.1). ...
the threonine side chain possesses a hydrophilic hydroxyl group that is capable of forming H-bonds, which can further affect ion permeation. To test this idea, we solved the crystal structure of the equivalent KpBest I180T mutant at 3.2 Å (Supplementary Fig.4a, Table2, Supplementary Tab...
