3G AraC-ssrA

AraC gene from the L-arabinose operon with an added ssra tag to allow for quicker endogenous degradation in e.coli. Represses pBAD promoter in the absence of arabinose. Gene flanked by prefix sticky end C and suffix sticky end D in a 3G-compatible backbone. For more information on 3G hybrid DNA assembly and 3G parts, see the [http://2018.igem.org/Team:William_and_Mary/Part_Collection William and Mary 3G Parts Page].

Compare to the coding sequence for AraC, BBa_K1088005: "This sequence is a copy of the sequence 70,387 -> 71,265 from E. coli K-12 MG1655 which is the coding sequence of the pBAD repressor araC.

From ECOCYC:

"The "arabinose regulator," AraC, is a transcription factor that regulates transcription of several genes and operons involved in arabinose catabolism and transport. It coregulates with another transcriptional regulator, CRP; both are transcription factors involved in l-arabinose degradation. These regulators bind cooperatively to activate transcription of five operons related to transport, catabolism, and autoregulation of l-arabinose. Transcription of these operons is induced when E. coli is grown in the absence of glucose and when the physiological inducer, l-arabinose, binds to the AraC regulator. In the absence of glucose, cellular cyclic AMP levels are high and cyclic AMP forms a dimeric complex with CRP to coregulate with AraC."
