Alignment of predicted calcium-binding lysozymes (Lysc1). Inferred amino acid sequences of predicted Lysc1 genes for diverse mammals are shown in the single-letter amino acid code. The DNA sequences are shown in Additional file 16: Figure S15. The number +1 identifies the N-terminal residue of the mature protein, and the signal peptides are shown in italics. The solid black triangles above the sequence indicate locations of the introns in the gene, with the exon number shown above the protein sequence. Dashes (-) identify gaps introduced to maximize alignment and refer to the absence of homologous sequence. Questions marks (?) indicate gaps introduced to maximize alignment, but are also potential sequence that may exist in sequence gaps in the genome assemblies (= missing data). Codons that have one or two base deletions, and thus would have a frame shift, are marked by an X. Asterisks identify in-frame stop codons in the sequences.
