Cutinase and polyhistidine tag

LC Cutinase coding sequence with polyhistidine tag attached. The polyhistidine tag allows our research team to perform assays to discover where our enzyme is being released, both in the media and in the cell.

Through p-nitrophenyl butyrate (pNPB) assays, the UC Davis team gathered enough data to determine that the LC-Cutinase part (BBa_K936000) incorporated in this part most likely exhibits its intended function as an esterase. Additionally, the Cutinase part with a pelB tag (BBa_K936013) has been found to be secreted from the cells expressing it. A detailed description of these assays can be found on the Module Engineering Project page: http://2012.igem.org/Team:UC_Davis/Project/Catalyst.


Western data of media samples probed for a his-tag shows that a protein of the length corresponding to cutinase (~30 kDa) is being secreted from the cell.


Quantitative measure of protein secretion into the media at different points after induction.


The above plots show the results on pNPB assays in which esterase activity is measured by the absorbance at 405 nm. It is clearly shown that the activity of cells expressing cutinase is much higher the background (negative control).
