The eIF4F and eIFiso4F Complexes of Plants: An Evolutionary Perspective
Figure 4
The H1-CT motif of eIF4G and eIFiso4G. Residues highlighted in green have identity to the shared core sequence RRx5KxIxExHxxA. The arrow identifies the site of the cum2 mutation in eIF4G. (a) The H1-CT motif of eIF4G. Residues highlighted in purple have identity to the unique residues of the eIF4G H1-CT motif RRVEGPKKI(D/E)EVHRDA. Genes of nonflowering plants and green algae are shaded grey. (b) The H1-CT motif of eIFiso4G. Residues highlighted in yellow have identity to the unique residues of the eIFiso4G H1-CT motif PRREExKAKTIxEHxEAExxLG. Genes of nonflowering plants and green algae are shaded grey. (c) The H1-CT motif of eIF4G genes of heterokonts, animals, and fungi. Residues are highlighted according to their identity to the shared core motif (green), the motif of plant eIF4G (purple), or the motif of eIFiso4G (yellow).
