Data statistics in DRAVP database. (A) The length distribution of antiviral peptides in DRAVP. (B) Hydrophobic content distribution of antiviral peptides. The hydrophobic content represents a ratio between total hydrophobic residues and total amino acids. (C) Number of antiviral peptides target various viruses. (D) Distribution of secondary structure in predicted structures. (E) Type of virus infection that the AVP used for treatment of clinical data. Among them, the number of entries used to treat COVID-19 and HIV infections is largest. (F) Source of antiviral proteins.
