Motif analyses of the Khib peptides. A Sequence logo of Khib motifs and conservation of Khib sites identified by the Motif-X program. The motif shows the Khib sites at the center and 10 amino acids upstream and downstream of the Khib site. The motifs with the significance of p < 0.000001 are shown. B Heatmap of the amino acid compositions of Khib sites. The intensity map shows the relative abundance of ± 10 amino acids from the Khib site. Colors represent the log10 of the ratio of frequencies within Khib-21-mers versus non-Khib-21-mers (red shows enrichment, green shows depletion)
