A Specific Feature of the Angiosperm Rab Escort Protein (REP) and Evolution of the REP/GDI Superfamily

Abstract

We found that a conserved arginine residue R195 known to be crucial for yeast REP function is substituted by an asparagine or threonine residue in angiosperm REPs. Evolution of the REP/GDI superfamily with a bi-functional REP/GDI protein as ancestor
