Figure 3.

Phylogenetic trees of family GH97. The trees were reconstructed by the PHYLIP package. Each node was tested using the bootstrap approach and the number of supporting pseudoiterations (out of 1000) is indicated for each internal knot. Subfamily belongings of sequences are indicated, the value of bootstrap support for each subfamily is coloured in yellow. Red arrows indicate to the enzymatically-characterized proteins 97A1_BACTH and 97A1_TANFO (see text). The origin of sequences is given in Table I. (A) The maximum parsimony phylogenetic tree. The bootstrap values were determined using the maximum parsimony (PROTPARS) method. (B) The neighbor-joining phylogenetic tree. The number of amino acid substitutions per site is taken as a measure of branch length.
