Characteristics of the 2-hydroxyisobutyrylated sites. (a) Conserved motifs of 2-hydroxyisobutyryl-21-mers flanking the modification sites (‘K’ in position 0). The size of each letter correlates to the frequency of that amino acid residue occurring in that position. (b) Frequency of each motif occurred in the identified 2-hydroxyisobutyrylated peptides. (c) Heat map of the amino acid compositions around the 2-hydroxyisobutyrylation sites. The –log10 (Fisher’s exact test p value) for every amino acid in each position (from −10 to 10) is shown. (d) Secondary structure and surface accessibility analyses of 2-hydroxyisobutyrylated lysine residues.
