pelB-LC-Cutinase fusion protein

pelB leader sequence attached to enzyme LC-Cutinase protein coding sequence in order to allow the cell to bring the enzyme to the periplasm for easier secretion.

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.
