Alignment of cathepsin D fragments. Quail database entry 15278 and part of 3793 (3793b) contained overlapping sequences and were both highly similar to chicken cathepsin D. Sequences confirmed by MS/MS sequencing are shown in red. Peptides identified only in one of the entries and not in the other one are underlined. Peptides matching only entry 3793b align to a gap in the alignment of this entry to chicken cathepsin D, and peptides matching only entry 15278 align to gaps in 3793b. Because of the very high sequence identity of both entries to chicken cathepsin D and the occurrence of several sequenced peptides shared by both entries we suggest that both entries are incomplete and likely belong to the same protein. Identical amino acid positions are shaded yellow
