ProEP-B2 was used in comparison to MatureEP-B2 to test whether or not the ProEP-B2 inhibitor was necessary for the protein to be expressed. However, our fluorescence assay showed that MatureEP-B2 grew sufficiently in spite of not having an inhibitor, meaning that the inhibitor in ProEP-B2 was not necessary. A fluorescence assay was performed to test presence of ProEP-B2 in SDS lysed E.Coli. The fluorescence assay showed that ProEP-B2 was found to be in cells, since the reading detected increasing presence of 5-FAM quencher in the samples, a quencher that is cleaved by the ProEP-B2 protein. (See [1] for details on the ProEP-B2 composite results). A fluorescence assay of the MatureEP-B2 in SDS lysed E.Coli was also performed, an assay that also successfully showed the presence of MatureEP-B2 in cells. The MatureEP-B2 was expressed at much higher RLU than the ProEP-B2, so it is possible that the inhibitor was responsible for the smaller expression found in ProEP-B2 compared to MatureEP-B2 (graphs shown below for comparison). More testing is needed to conclude that the inhibitor was responsible for the difference in expression.
