Fig. 1. Alignment of AgCA9 with AgCA6, AgCA10 and AgCA11, formally cloned by the
Linser laboratory. Also included are Homo sapiens CAII (HCAII) and
Drosophila melanogaster CAI (DrosCAI). Alignment was performed in
ClustalX and visualized using Genedoc. Similarity groups were enabled using
the default scoring matrix, Blosum 62 matrix. Regions with high similarity are
highlighted in blue (100%). Regions of lesser similarity are highlighted in
red (>80%) and yellow (>60%). The three histidines essential for
-CA activity are indicated with a star (HCAII his-94, his-96, his-119).
The black bars indicate antigenic sites against which antibodies (5340 and
5563) were generated.
