Thioesters are common intermediates in many biosynthetic reactions, including the formation and degradation of fatty acids and mevalonate, precursor to steroids. Examples include malonyl-CoA, acetoacetyl-CoA, propionyl-CoA, cinnamoyl-CoA, and acyl carrier protein (ACP) thioesters. Acetogenesis proceeds via … See more In organic chemistry, thioesters are organosulfur compounds with the molecular structure R−C(=O)−S−R’. They are analogous to carboxylate esters (R−C(=O)−O−R’) with the sulfur in the thioester replacing … See more Thionoesters are isomeric with thioesters. In a thionoester, sulfur replaces the carbonyl oxygen in an ester. Methyl thionobenzoate is C6H5C(S)OCH3. Such compounds are typically prepared by the reaction of the thioacyl chloride with an alcohol. See more The most typical route to thioester involves the reaction of an acid chloride with an alkali metal salt of a thiol: Another common route entails the displacement of See more Thioesters hydrolyze to thiols and the carboxylic acid: RC(O)SR' + H2O → RCO2H + RSH The carbonyl center in thioesters is more reactive toward … See more • Thiocarboxylic acid • Liebeskind-Srogl coupling • Aldrithiol-2 See more WebThe classical pathway is normally triggered by antigen–antibody complexes that bind the C1 complex (C1q, C1r, C1s) through the C1q component. This activates C1s, which is then able to cleave the C4 complement protein into C4a and C4b. C4b attaches to its target surface via its exposed metastable thioester binding site.
WebApr 6, 2024 · The protease cleavage of a largely disordered bait region activates CD109, resulting in a conformational change that traps the protease in a cage-like structure and exposes the highly reactive thioester bond.
