Figure 3

Maximum likelihood reconstruction of PEPCK gene phylogeny. Numbers at edges are bootstrap support values from 1000 iterations using a JTT amino acid substitution model in PHYML [15]. Sequences were bootstrapped and iterations compiled with SEQBOOT and CONSENSE from the PHYLIP package [16]. Abbreviations are those of Figure 2 plus: mycobact, Mycobacterium sp. (Eubacteria); sulfolob, Sulfolobus sp. (Archaea); danio, Danio rerio (zebrafish); salm, Salmo salar (salmon); gallus, Gallus gallus (chicken); bost, Bos taurus (cattle); mus, Mus domesticus (housemouse); hsap, Homo sapiens (human).
