Figure 2.

Sequence alignment of GlcAT-P with putative proteins in C. elegans and S. mansoni. Black and meshed backgrounds indicate identical and similar residues, respectively. Dashes indicate gaps introduced for maximal alignment. Boxes indicate transmembrane regions. The amino acid sequence of S. mansoni was deduced from the cDNA sequence registered in a DNA data bank (GenBank). Four highly conserved regions were named as motifs I–IV, and their locations are indicated by arrows.
