^aSimilar tables have been provided in Datta et al. (2008), and Yin et al. (2015).

^bThese proteins have been purified and characterized for DNA binding and nuclease activities in vitro.

^cThese systems were tested in E. coli for ssDNA recombineering.

^dThese systems were tested in E. coli for ssDNA and dsDNA recombineering.

^eICE: integrating conjugative element (a mobile genetic element).

^fThe RecT1 protein from L. reuiteri was also tested in L. lactis, L. gasseri, and L. plantarum.

^gFor these SSAPs only ssDNA recombineering was tested.

^hThe recT homolog from C. perfringens was tested for ssDNA recombineering in C. acetobutylicum.
