Out of the total 45,120 peptides in the StarPep database, 13,437 of them are labelled as having antimicrobial properties (Fig. ). StarPep aggregates bioactive peptides from over 40 existing datasets featuring peptides with sequence lengths between 2 and 100 amino acids. After removing from the dataset the 15% of the peptides featured in StarPep with sequence lengths greater than 50 amino acids and peptides with non-standard amino acids, we retained 35,806 of the original 45,120 sequences, of which 10,841 are labelled as having antimicrobial properties. The remaining 24,965 peptides from Starpep did not have the label Antimicrobial.
