RecA filament sliding on DNA facilitates homology search

FReebie! RecA almost sounds like a sentient being.

Or very well designed.

Not to rain on their parade but 99% of this stuff about RecA has been known for 40 years. My graduate advisor worked on this enzyme in the 60’s. Its one of the best understood DNA repair enyzymes and has been for decades.

Interesting, this might as well explain why the repair mechanism sometimes does not work and lead to cancer. The bacterial RecA is homologous to the mammal Rad51-related protein family that participates in homologous recombination to maintain chromosome stability and repair DNA damage. It is highly conserved, and thus have a very high importance in most eukaryotes, from bacteria to humans.
