This suggests that in each of these cases a RecT superfamily gene was inserted in frame into a pre-existing ERF gene leaving behind only a non-functional fragment of it (Fig.
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.
RecT and Redβ are evolutionarily related and define a widespread family of DNA recombination proteins
For example, searches initiated with the Redβ homolog, PF161 protein (Genbank gi: 9836834 amino acids 1 to 188) from Borrelia hermsii [ 18 ] , detected the E. coli RecT protein in the 5 thiteration with significant expectation (e) values (3 × 10 -3).
Genes for RecT/Redβ superfamily proteins are associated with genes encoding a λ-type exonuclease (LE) of the type II restriction enzyme fold, RecE, which also might be a divergent member of this fold, and a nuclease of the Endonuclease VII (EndoVII) fold [ 7 34 ] (Fig.
