Figure 1.

Sequence alignment of Pex7p and Pex20p. (A) Amino acid sequences of Pex7p from N. crassa, S. cerevisiae, and P. pastoris were aligned with DNAMAN (Lynnon BioSoft, Quebec, Canada). Identical residues in all three sequences are shaded in black. Residues that are either similar in all three sequences or identical in two out of three sequences are shaded in gray. Similarity rule: D = E, R = K, Q = N, S = T, I = L = V = A. (B) Amino acid sequences of Pex20p from N. crassa and Y. lipolytica were similarly aligned, but only identical residues (shaded in black) are shown. The box marks the region within Pex20p that is conserved in Pex18p and Pex5pL.
