Figure 2: Amino acid alignments for C-terminal 11-residue repeat sequences for mammalian CEL subunits. Hydrophobic amino acid residues are shown in red; hydrophilic residues in green; acidic residues in blue; basic residues in pink; (squared T) refers to known O-glycosylation sites for human CEL; R refers to repeat number. P-proline; V-valine; T-threonine; G-glycine; D-aspartate; E-glutamate; S-serine; A-alanine; K-lysine; N-asparagine; note consistent PVPP start sequences.
