Fig. 5: Summary of VAR2CSA DBL domain architectures.

a Schematic of the DBL domain composition of a typical VAR2CSA with NTS-DBL1X-6ɛ is represented. Atypical structures of VAR2CSA consisting of b NTS-DBL1X-7ɛ and c NTS-DBL1X-6ɛ domain combination, and d the truncated var2csa (with NTS-DBL1X structure) are shown. The number of analyzed isolates displaying the different architecture of VAR2CSA are indicated.
