Plac + RBS + cxnA (cex + cenA fusion)

Lac promoter and RBS, followed by Cex exoglucanase from Cellulomonas fimi fused to CenA endoglucanase from the same species. The coding sequence contains, in order:

  • The GH10 exoglucanase domain
  • A (possibly inactivated) cellulose binding domain
  • The GH6 endoglucanase domain


In the process of creating this part, we (Edinburgh 2011) tested putative correct clones on carboxymethylcellulose (CMC) plates, with Congo red dye. This test produces a zone of clearing if CMC is degraded by endoglucanase:

Evidently we had three correct colonies, here numbered 8, 17, and 22. These had already been tested for their ability to degrade MUC, in an assay similar to that for BBa_K523016. Thus, both the exoglucanase and the endoglucanase domains have been shown to work.
