After the SP region (orange) was identified using SignalP 4.1 for positive data or a fixed length of 30 amino acids for negative, five modifications were made to each original sequence in a dataset. Reverse inverted the amino acid order of the entire sequence; SP C-term placed the SP at the C-terminus, leaving the sequence length unchanged; SP Remove excluded the SP region and shortened the sequence length. SP Random and Random involved random shuffling of the SP region and the entire coding sequence, respectively. The sequences were then submitted to SecretomeP. Orange, SP region; Purple, mature protein sequence.
