From: Evolutionary insights about bacterial GlxRS from whole genome analyses: is GluRS2 a chimera?
Evolutionary model of bacterial and eukaryal GlxRS. The N-terminal catalytic and the C-terminal anticodon-binding domains of GlxRS are annotated by the letters N and C, and depicted according to their mutual homology (oval: N-terminal domains of all GluRS and GlnRS; diamond: C-terminal domains of all GlnRS and eukaryal GluRS; square: C-terminal domains of bacterial GluRS). tRNAGlx-aminocylation specificities of GlxRS are indicated by color-coded shades. HGT and ‘?’ stand for horizontal gene transfer and ‘open questions’, respectively.
