Fig. 8From: Peptides derived from Kex2-processed repeat proteins are widely distributed and highly diverse in the Fungi kingdomTaxonomic tree of strains containing Kex2-processed repeat proteins (KEPs) homologous to the ustiloxin precursor peptide. Core peptide sequences deduced from those of ustiloxins and phomopsins are shown next to the strains. Red arrow indicates the POI2 protein, which is experimentally shown to be involved in sexual structure formation in Neurospora crassaBack to article page
