2i2O Protein Evolution Presentation

• Evolution of eIF4G occurred early on in euks

• Evolution of three domains within eIF4G - MIF4G being one of them

• Research indicates all three domains present in early euks

• Possible loss of these domains within other organisms

• Three programs used to construct phylogenetic tree

• Blast used to find significant sequences

• 54 sequences chosen because E-value under 0.01

• ClustalX used

• Multiple alignment of the 55 sequences undertaken

• First draft phlogenetic tree created
