title: Nepsilon-thioacetyl-lysine: a multi-facet functional probe for enzymatic protein lysine Nepsilon-deacetylation.
abstract: Peptides containing Nepsilon-thioacetyl-lysine and Nepsilon-acetyl-lysine were evaluated for their de(thio)acetylation catalyzed by human HDAC8 and SIRT1, two distinct protein deacetylases. Nepsilon-Thioacetyl-lysine was found to be a mimic of Nepsilon-acetyl-lysine for HDAC8-catalyzed reaction, but to confer inhibition against SIRT1. These results point to further diverse applications based on Nepsilon-thioacetyl-lysine.
