This is the N-terminal domain of ToxB found in Pyrenophora tritici-repentis. This domain is crucial for toxin activity. There are only two amino acid differences between ToxB and toxb, an inactive homolog of ToxB. These two differences are a Val at position 3 in ToxB compared to a Thr in toxb, and an Ala at position 12 in ToxB compared to a Val in toxb. AvrPiz-t, a secreted avirulence protein produced by the rice blast fungus, is a structural homolog to ToxB [1].
