Sequence analysis, multiple sequences alignment and phylogenetic analysis
The searches for nucleotide and protein sequence similarities were conducted with BLAST algorithm at the National Center for Biotechnology Information (NCBI, http://www.ncbi.nlm.gov/blast). The deduced amino acid sequence of EsCypA was analyzed with the Expert Protein Analysis System (Expasy, http://www.expasy.org/). SignalP 3.0 program was utilized to predict the presence and location of signal peptide (http://www.cbs.dtu.dk/services/SignalP/). The protein motif features were predicted by Simple Modular Architecture Research Tool (SMART) version 7.0 (http://smart.embl-heidelberg.de/). Multiple sequence alignment of EsCypA and other reported Cyps was performed with ClustalW multiple alignment program (http://www.ebi.ac.uk/Tools/clustalw2/) and multiple alignment show program (http://www.bioinformatics.org/sms/). An unrooted phylogenic tree was constructed based on the deduced amino acid sequences of EsCypA and other reported Cyps by the neighbor-joining (NJ) algorithm using the MEGA 5.05 software (http://www.megasoftware.net). To derive the confidence value for the phylogeny analysis, bootstrap trials were replicated 1000 times.
