FIG. 2.

Amino acid sequence alignment of the acidic amino acid permeases of P. chrysogenum (PcDip5) and S. cerevisiae (Dip5) (33) and putative acidic amino acid permeases of A. nidulans (AnDip5) and Kluyveromyces lactis (KlDip5). The A. nidulans sequence, 57% identical to that of PcDip5 and 50% identical to that of Dip5, was derived from the A. nidulans database of the Whitehead Institute after a BLAST search (2). This sequence is incomplete at the N terminus. The K. lactis sequence was obtained after a BLAST search at the National Center for Biotechnology Information; it shares 61% amino acid identity with Dip5 and 50% identity with PcDip5. Conserved and similar amino acids are highlighted in black and grey, respectively.
