  1. aEach tryptophan congruency group (TCG) defined by the concatenated tree for Trp proteins (Fig. 2) is congruent with the color-coded subtree section within the 16S rRNA tree (Fig. 1). Organisms that are included in the concatenated tree of Fig. 2 are indicated in boldface type, whereas additional organisms not included in the concatenated tree but that were qualitatively determined to belong to a given TCG are indicated in regular type. bTCG members originating by LGT are indicated within brackets and indented. cInsect symbionts. dThe five organisms marked with asterisks form a distinctive subclade that is, in fact, not a "pure" component of TCG-2 because of the LGT origins of trpEa and trpEb from TCG-3 (see text). eAll members of TCG-5 lack trpC and presumably utilize a dual-pathway hisA (priA) for this function.
