Sketch of sequence-based encodings derived from autocorrelation and reduced amino acid alphabet. a Autocorrelation and pseudo-amino acid composition from adjacent residues, considering a gap size of one. b Reduced amino acid alphabet. Clustering corresponds to similar physicochemical properties, according to Veltri et al. (2017)
