Figure 1From: Evidence for a rapid rate of molecular evolution at the hypervariable and immunogenic Mycobacterium tuberculosis PPE38 gene regionPhylogenetic reconstruction of the evolutionary relationships between members of the H37Rv M. tuberculosis PPE protein family members. The phylogenetic tree was constructed from a phylogenetic analysis done on the 180 aa N-terminal domains of the PPE proteins. Results show the division of PPE proteins into 5 sublineages with PPE38 (Rv2352c, highlighted in green) located at the border of sublineages IV (SVP subfamily) and V (MPTR subfamily).
