Phylogenetic analysis of sulphate permeases of H. jecorina. Sulphate permeases present in the genome of H. jecorina and their nearest neighbours were analyzed with the software MEGA 4 using the Minimum evolution method. Description and GenBank accession numbers of the proteins used are listed in Table 1. H. jecorina sulphate permeases are provided with the proteinID as given in the T. reesei genome database v2.0. Numbers at branches indicate their boostrap support. Clusters comprising homologues of N. crassa CYS-13 and CYS-14, respectively, are boxed.
