Sequence frequency analysis of the three KAT families acetylated peptides.
A, B, and C, Frequency analysis of acetylated peptides of the three KAT families as indicated in the figure. D, All validated acetylated lysine (AC-K) peptides including those without KAT information. Sequence logo plots represent amino acid frequencies for 8 amino acids from both sides of the lysine acetylation site. N: amino side. C: carboxyl side. AC-K: acetylated-lysine. Number of peptides in each family: CBP/p300 280, GCN5/PCAF 84, MYST 20, All validated 4483.
