Plac + RBS + cex (exoglucanase)
This is C. fimi exoglucanase under the control of the Lac promoter. This was made by Edinburgh 2008 but vector-swapped into pSB1C3 and entered into the Registry by Edinburgh 2011.
Characterization
Edinburgh 2011 conducted two assays, comparing the activity of this part to a β-glucosidase (E. coli bglX, BBa_K523014, also under the control of the lac promoter) on two different substrates:
- 4-methylumbelliferyl β- D- glucuronide (MUG, left photo). This substrate is a cellobiose analog.
- 4-methylumbelliferyl β- D- cellobioside (MUC, right photo). This substrate is larger and is more like a cellulose analog.
Both substrates produce a fluorescent product when cleaved. Our plates below show the results of placing cell lysate and cell debris on an MUG plate and an MUC plate. Present on both plates are:
- Left side of plate: lysate/debris from JM109 expressing bglX, BBa_K523014
- Right side of plate: lysate/debris from JM109 expressing cex, BBa_K523016
- Bottom of plate: lysate/debris from JM109 cells
MUG assay. bglX on left, cex on right. | MUC assay. bglX on left, cex on right. |
As can be seen, cex is much better at degrading MUC.
