This allow user to compare a given sequence of protein in different strains of Mycobacterium at a chosen threshold of similarity. This module works on the basis of BLAST algorithm, based on sequence identity, wer process the sequence. Here, user can select the sequence identity cut-off not only for mycobacterial strain, but also for human proteome. This will help user to select a sequence shared among the different strains, but not shared in human proteome. Therefore, this module is very important for the selection of important vaccine candidates.
