... Apparently, if paralogous TFs maintain overlap-
ping DNA binding specificities, then a single site can evolve to
bind both TFs. As the evolution of these sites relies on the
functional similarity of the ... that relatively few of the TFs
evolved by duplications within the E. coli lineage. Instead, we
found a surprisingly complex history of HGT for many of the

... specific and

regions of housekeeping genes, then we would expect them to
be ... simply as enrichment in GC-rich domains.
We find that the enrichment is best explained as being in the
vicinity of housekeeping genes. Is it the case, then, that Alu...
