Representative domain architectures for calpain homologues. Domain architecture diagrams were downloaded from the Pfam website (http://pfam.xfam.org). Diagrams are shown in the same order as they occur in Fig. 1, starting with homologues from bacteria and proceeding in a clockwise direction. The UniProt identifier for each protein is shown on the left. In each domain architecture diagram sequence length is indicated by the horizontal grey line (the “string”): sequence lengths are approximately proportional to one another. Domains are shown in the order they appear in the sequence as “beads on a string”. A domain with rounded ends is complete; a domain with a ragged end matches only a fragment of the complete domain as defined in Pfam. All calpain domains are shown in green and labelled “peptidase C2”; other domains are shown in other colours. Small rectangles indicate transmembrane regions (pink), disordered regions (grey), regions of low complexity (pale blue), and regions of coiled-coil (green). Blue “lollipops” at the top edge of a domain indicate active site residues (in the order Cys, His, Asn). Carbohydrate attachment sites are shown as square-topped lollipops at the bottom edge of a domain (where known). Key to sequences (unp = unnamed protein, domains are shown as strings with each domain separated by a tilde, pC2 = calpain domain): E5XTU0_9ACTO, unp (Segniliparus rugosus strain ATCC BAA-974), pC2; E5C759_9BACE, unp (Bacteroides sp.
