Fig. 1From: The peptide transporter 1a of the zebrafish Danio rerio, an emerging model in nutrigenomics and nutrition research: molecular characterization, functional properties, and expression analysisPairwise alignment between zebrafish PepT1a (Slc15a1a) and PepT1b (Slc15a1b) amino acid sequences obtained by using Clustal Omega and edited using GeneDoc 2.7 software. The predicted conserved PTR2 family proton/oligopeptide symporter signatures (in zebrafish PepT1a, motif 1—PROSITE pattern PS01022—amino acid residues 80–104; and motif 2—PROSITE pattern PS01023—amino acid residues 173–185) are colored in red. In the amino acid sequence, putative transmembrane domains are named I to XII. Weak predicted transmembrane domains (in zebrafish PepT1a, transmembrane domains VIII and X) are colored in grayBack to article page
