Analysis of CKM C-terminal peptide 364EKKLEKGQSIDD375: (i) phosphorylated at Ser-9 (Ser-372; KXXpS) or (ii) acetylated at Lys-6 and phosphorylated at Ser-9 (Lys-369 and Ser-372; AcKXXpS) by two-dimensional 1H NMR total correlation spectroscopy (TOCSY) and NOESY. Overlays of HA-HN TOCSY region of acetylated (AcKXXpS) and nonacetylated (KXXpS) phosphopeptide are shown in A; HB-HN TOCSY and NOESY regions of the acetylated phosphopeptide (AcKXXpS) are shown in B; side chain NOESY region of the acetylated (AcKXXpS) and nonacetylated (KXXpS) phosphopeptide is shown in C. D, proposed conformation of the acetylated (AcKXXpS) and nonacetylated (KXXpS) phosphopeptide.
