  1. The E. tenella genome database (http://www.genedb.org/Homepage/Etenella) was searched for genes predicted to code for proteins with peptidase activity. All auto-annotated peptidase genes identified were manually curated by performing BLAST analysis against apicomplexan genome sequence databases and various protein databases [32] such as the protein data bank (PDB), Swiss-Prot and non-redundant (NR). In addition, signature protein motifs for the protein sequence of each gene were identified through Pfam (http://pfam.sanger.ac.uk/search; [33]), InterproScan (http://www.ebi.ac.uk/Tools/pfa/iprscan/) and the MEROPS databases (http://merops.sanger.ac.uk/; [34]). Further gene sequence manipulations, such as translation into amino acid sequences and ClustalW alignments, were performed using the DNASTAR Lasergeneâ„¢ 9 Core Suite. Genes were assigned a five-tiered level of confidence for gene function using an Evidence Rating (ER) system giving an overall score of ER1-5, where ER1 indicates extremely reliable experimental data to support function and ER5 indicates no evidence for gene function [17].
