Motif analysis of the identified acetylation peptides. a Probable sequence motifs of acetylation sites in fatty liver tissues identified using Motif-X. b Number of identified peptide containing acetylated lysines and their probable motifs. c Heat map showing the relative frequencies of amino acids in specific positions, including enrichment (red) or depletion (green) of amino acids flanking the acetylated lysine in fatty liver proteins. d Location probabilities of acetylated and/or non-acetylated lysines in protein secondary structures (alpha-helix, beta-strand, and coil) and surface accessibility
