Comparison of phylogenetic trees constructed using (a) the kernel-based method and (b) the alignments of the following two enzyme sequences, together: phosphoglycerate kinase (EC 2.7.2.3) and phosphopyruvate hydratase (EC 4.2.1.11). The amino acid sequences of corresponding enzymes were retrieved from the GenBank database and analyzed by CLUSTAL with default parameters. The resultant trees were viewed with the TREEVIEW program [43].
