Figure 6: Phylogenetic tree of methyl-accepting chemotactic proteins (MCP) homologues in completed genomes.
From: DNA sequence of both chromosomes of the cholera pathogen Vibrio cholerae
Homologues of MCP were identified by FASTA3 searches of all available complete genomes. Amino-acid sequences of the proteins were aligned using CLUSTALW, and a neighbour-joining phylogenetic tree was generated from the alignment using the PAUP* program (using a PAM-based distance calculation). Hypervariable regions of the alignment and positions with gaps in many of the sequences were excluded from the analysis. Nodes with significant bootstrap values are indicated: two asterisks, >70%; asterisk, 40–70%.
