    Product Description

    SAMS peptide is a synthetic peptide substrate for AMPK based on the sequence around Ser79 (which is phosphorylated exclusively by AMPK) on acetyl-CoA carboxylase.1 In this sequence, Ser77 (which is phosphorylated exclusively by PKA) is replaced by alanine to eliminate a neighboring binding site for PKA.1 This substitution yields a substrate more specific for AMPK than acetyl-CoA carboxylase itself. SAMS peptide is phosphorylated rapidly by AMPK, providing a convenient and sensitive tool for assaying AMPK activity.2
