Percentage of transmembrane proteins, containing at least one of the 58 non-redundnat, fully characterized sequence motifs, for each species. Only the top 10 mostly represented species, oredered by the number of motif hits in the dataset of transmembrane proteins are reported. The first colomn specifies the protein species, the second colomn specifies, for each species, the number of motif hits in Swiss-Prot transmembrane sequences, the third colomn specifies, for each species, the number of corresponding transmembrane protiens in Swiss-Prot and the last colomn shows, for each species, the percentage of transmembrane protein that contains at least one motif.
