Depositor Comments

iGEM parts BBa_B1002 and BBa_B1006 were used to build the double terminator element. The trimethoprim resistance gene was taken from EZ-Tn5™ <DHFR-1> (Epicentre). We developed GetX (https://sourceforge.net/projects/getx/) a stand-alone python script that allows the user to design mutation cassettes for scarless genome editing in bacteria using our previously described two-step recombination method. Please see the document linked under the Resource Information heading above for additional information on installing and using the script.
