Testing matlab substrate specificity of Sirt3 and Sirt5 with peptides. a Sirt3, but not Sirt5, deacetylates matlab fluorogenic peptide QPK acetylK. b Sirt3 effectively deacetylates matlab fluorogenic peptide RHK acetylK, and Sirt5 also considerably deacetylates this substrate. 0022283608009029 gr1. jpgIn order to identify novel physiological substrates engineering matlab mitochondrial Sirtuins, we used proteins remoted of their partly acetylated form from natural sources i. e.
