Comparison of tau class GST proteins from T.
tauschii. A, Alignment of the deduced amino acid sequences of
TtGSTU1, TtGSTU2, and TtGSTU3.
Identical amino acids and conservatively substituted residues are
shaded with light and dark gray, respectively. The amino acid residue
where exon 2 of TtGSTU1 and TtGSTU2 starts is
indicated by an asterisk above the sequences. GenBank accession numbers
are as follows: TtGSTU1 and TtGSTU2 (AY013753),
and TtGSTU3 (AY013754). B, Hydropathy profile of the
TtGSTU1 protein, as determined by the method of Kyte and
Doolittle (1982) using a window of 10 amino acid residues.
