Exploring the biological roles of Dothideomycetes ABC proteins: Leads from their phylogenetic relationships with functionally-characterized Ascomycetes homologs - Fig 1

<p>Schematic representation of: A) Canonical structure of ABC proteins. Walker-A, ABC-signature and Walker-B are characteristic motifs found in all ABC ATPases. B) The typical mechanism of an ABC exporter. C) Predicted topology and domain organization in different subfamilies of fungal ABC proteins.
