Thiol removal
WebAug 11, 2014 · Thiols are also more nucleophilic than alcohols, especially in basic solution. Thioethers are in general formed by reaction of the thiol, in a basic solution, with a halide. Much of the chemistry used for the protection of a thiol can also be used for the protection of the selenol group, which is not nearly as common in organic synthesis, but ... WebMar 6, 2024 · Binding of proper substrate results in activation of the thiol (removal of the proton by the histidine group). The activated thiol acts as a nucleophile, attacking the peptide bond and causing it break. One peptide is released and the other peptide becomes covalently linked to the sulfur. Hydrolysis by water releases the second peptide and ...
