Part:BBa_K1065001
AraC-pBAD + 2-oxoglutarate oxygenase/decarboxylase (EFE) + terminators
This is a composite part composed by an AraC-pBAD promoter (BBa_K731201) + 2-oxoglutarate oxygenase/decarboxylase (BBa_K1065000). This construct allowed us to characterize the Ethylene Forming Enzyme, inducing its expression using Arabinose at a concentration of 5 mM.
EFE characterization
In order to obtain a good characterization of the part, a set of experiments were done.
Effect of EFE on cell growth
Figure 1 Effect of EFE on cell growth. Cell density was measured at different time points to determine the effect of EFE expression. Cells were grown at 37 °C in LB until it was reached an OD of 0.6. The cells were then slitted in four samples of equal volume. Two samples were then induced with 5 mM Arabinose. Induced samples show a slowed growth rate, as espected (5mM arabinose is a strong induction that causes stress on cells). However, cell growth is not completely inhibited so EFE is not highly toxic
