Figure 4.

Alignment of a set of 11 proteins by (A) ClustalW and (B) DbClustal. The N- and C-terminal extensions in both alignments are not shown. The corresponding segments in the ClustalW alignments are shown for comparison purposes. The regions denoted by the blue arrows below the DbClustal alignment correspond to the blocks detected by the Probe program. Ten homologues were detected by Probe, with four sequences being included in the final model alignment. These are indicated by the underlined names.
