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.
