Characterisation

This part was co-transformed with EutLK-Low-PduD-mCherry-PPK (https://parts.igem.org/Part:BBa_K2213013) to form EutSMNLK+Low_PduD+PPK, and is characterized as follows.

A 24 hour induction was DAPI stained to determine microcompartment formation and tag localisation.

DAPI staining and mCherry fluorescence within E.coli appear to colocalised, and locally enriched to foci at particular sub-cellular sites (Figure 2). This heterogeneous distribution of mCherry is induced by the presence of promoter-PduD-mCherry-PPK, with controls lacking the PPK element showing largely ubiquitous mCherry fluorescence throughout the cell (Figure 3). We conclude these results to indicate successful tag localisation and by proxy successful expression of Eut subunits.
