Differences between Mtu strains
From DrugPedia: A Wikipedia for Drug discovery
There are several ways to look at pairwise differences between Mtu strains:
- pairwise differences in the nucleotids of the genomes
- pairwise differences in the amino acid sequences
- pairwise proteomic differences (orthologs, missing genes, gene doubling, additions like prophages)
- pairwise functional differences where known
Since we now have complete genomes of several strains of Mtu, and we have pairs of orthologs for both from a highly accurate algorithm (OMA), and the highly correct phylogenetic trees from OMA show us which strains are nearest, we can most easily give orthologs and paralogs between nearest pairs of strains.
