Motif annotation
The motifs were identified using the Expasy ScanProsite (50) API (Application Programming Interface) with the help of a Python script. ScanProsite tool takes into account the ProRules which focuses on extreme similarity at only a few biologically significant sites of well-chosen residues i.e motifs or signatures and also defines the position of these structurally and functionally crucial amino acids. The rules are further used internally, by the Swiss-Prot for annotation of protein query sequences. The motif information for each protein was collected in the form of ScanProsite IDs, motif name and pattern.
