Maximum likelihood tree for the RecT/Redβ superfamily of proteins. The internal branches with RELL bootstrap support >70% are indicated by blue circles. Proteins are designated by their gene names and species abbreviations as in Fig. 1. The gene neighborhoods of the RecT/Redβ superfamily genes are shown in association with the corresponding branches whenever they they contained genes for proteins with plausible functional connections with SSAPs. The hatched boxes represent fragments of ERF (Indicated by E) and SSB (indicated by S) genes encoding C-terminal regions as described in the text. Gene abbreviations are as follows: GP46: GP46 of bacteriophage PSA, GP32:GP32 of bacteriophage PSA, ORF15:ORF15 of Streptococcus thermophilus bacteriophage 7201, ORF40: ORF40 of bacteriophage PVL ORF86:ORF86 of Staphylococcus aureus temperate phage φSLT, Orf100a:0rf100a of Staphylococcus aureus temperate phage φSLT, ORF364: ORF364 of bacteriophage φ31.1, Ec2360: b2360 of E. coli, AcylTr: N-Acyltransferase, Bro: Bro-N domain fused to XF0704, Met: DNA Methyltransferase
