You might get tired of hearing this, but I did another KREd + MAP7 transformation today.
I'll be making RecJdprA-- and ExoIdprA-- double mutants this week.
I'll also attempt to read through papers on ExoI, RecJ, and DprA and their functions in recombination. I've been through one paper so far, and the most I got out of it was something about UV radiation and maintaining something or other and ... I guess I'll try to read it again tomorrow.
