Figure 1

Multiple sequence alignment of the RecT/Redβ superfamily of proteins. Proteins are denoted with their gene names, species abbreviation and gi numbers. The coloring reflects the amino acid conservation at 85% consensus. The consensus abbreviations and coloring scheme are as follows: h: hydrophobic residues (L,I,Y,F,M,W,A,C,V), l: aliphatic (L,I,A,V) and a: aromatic (F,Y,W,H) residues shaded yellow; o: alcohol (S,T), colored blue, c: charged (K,E,R,D,H) residues, +: basic (K/R/H) residues, -: acidic (D,E) residues, and p: polar (S,T,E,C,D,R,K,H,N,Q) residues colored purple; s: small (S,A,C,G,D,N,P,V,T) and u:tiny (G,A,S) residues, colored green; b: big (L,I,F,M,W,Y,E,R,K,Q) residues shaded gray. Secondary structure assignments are as follows: H: Helix, E: Extended (Strand). Species abbreviations are as follows: Bh: Bacillus halodurans, Borhercp: Borrelia hermsii circular plasmid, BPA118: Bacteriophage A118, BPbIL309: Bacteriophage bIL309, BPphi31_1: Bacteriophage phi31.1, BPPVL: Bacteriophage PVL, BPR1T: Bacteriophage R1T, Bs: Bacillus subtilis, ec: Escherichia coli, lambda: Bacteriophage λ, Li: Listeria innocua, Lp: Legionella pneumophila, Ml: Mesorhizobium loti, Salent: Salmonella enterica subsp. enterica serovar Typhi, SaN315: Staphylococcus aureus N315 subsp. aureus N315,Sd: Shigella dysenteriae, SPP1: Bacteriophage SPP1, StLT2: Salmonella typhimurium LT2, Strpy: Streptococcus pyogenes, Uu: Ureaplasma urealyticum, Xf; Xylella fastidiosa
