Figure 7From: Evolutionary mechanisms driving the evolution of a large polydnavirus gene family coding for protein tyrosine phosphatasesPositively selected sites in PTP EX subclade. In the alignment, PTP EX sequences are represented with the same amino acid numbering to facilitate comparisons. Structural motifs identified in Vertebrate PTPs are indicated. Variable regions α1/β1 loop, α5-loop-α6 and sites involved in substrate specificity (noted S) are mentioned. Stars indicate sites significantly shown to evolve under positive selection.Back to article page
