Histograms showing the fraction of in-vitro acetylation at Lys-14, Lys-64, Lys-66, Lys-70 and Lys-73 of recombinant HMGA1a and phosphorylated HMGA1a (phos-HMGA1a) catalyzed by both p300 and PCAF (top panel), and the fraction of in-vitro acetylation at Lys-14, Lys-53, Lys-55 Lys-59 and Lys-62 of recombinant HMGA1b and phosphorylated HMGA1b (phos-HMGA1b) catalyzed by both p300 and PCAF (bottom panel).
