Figure 4.
Amino acid alignment of A. gambiae class I GST cDNAs. Gaps introduced to maximize sequence identity are shown by a horizontal dash. ∗ indicates the presence of an identical residue in all six A. gambiae GSTs. Residues in bold are shared by all 27 Dipteran class I GSTs within GenBank. The five residues in bold italics are shared by all known insect GSTs. A vertical arrow marks the junction between exon 2 and exon 3 in aggst1-3, aggst1-4, aggst1-5, and aggst1-6.
