Indeed, a correlation between EC50 values and quantum mechanics simulations strongly suggests the existence of a cation-pi interaction between a triptophan residue of the ligand binding pocket and the quaternary ammonium of acetylcholine [ 9 ] . A series of grid representations of the ligand binding pocket was generated that accounted for Van der Waals shape, electrostatic potential, as well as hydrogen bonding and hydrophobicity profiles.
Rad52 functions in conjunction with the RecA ortholog, the RAD51 recombinase in double-strand break repair and meiotic recombination [ 6 ] . RAD52 binds ssDNA during recombination and also shows a quaternary organization similar to those of RecT/Redβ and ERF [ 16 26 ] . However, RAD52-like proteins showed no detectable sequence similarity with either the ERF or the RecT/Redβ-like proteins.
We show that, in spite of the functional similarities, and the similar quaternary structures, there are three distinct superfamilies of SSAPs, namely the RecT/Redβ, RAD52 and ERF, that appear to be evolutionarily unrelated to each other.
The ERF protein of phage P22 is involved in the circularization of the linear dsDNA phage genome upon entry into the host cell [ 21 22 23 ] . Experimental studies have shown that, mutations in ERF are complemented by Redβ and that in vitro ERF adopts quaternary structures analogous to those of Redβ and RecT [ 14 17 24 25 ] . However, in the comprehensive analysis of the RecT/Redβ superfamily no statistically significant similarity could be detected between these proteins and the ERF proteins.
Hypothesized migrations out of northern Asia purportedly occurred along three lines: 1) westward into Europe, with gradual migration into North America, western Asia, Asia Minor, the Mediterranean, and Africa; 2) eastward into Siberia into western North America, and into eastern Europe; and 3) further south into Asia primarily during the Quaternary.
