Strong Promoter Strong RBS lldR+lldD
This construct has L-Lactate Dehydrogenase (lldD) and Regulator element (lldR) under the control of a strong promoter and a strong RBS. lldD cleaves L-Lactate to pyruvate and lldR has the dual role of an activator and a repressor. Our intention of using this part is to have control over the detection threshold of L-Lactate by the lldPRD regulatory region. We have also designed other parts which produce various lower concentrations of lldD and lldR by varying the strength of the promoter and RBS controlling their production.

Characterization
During the course of our experiments, we had some technical difficulties with SOEing, but we got the constructs after a few attempts. The SOEed construct was digested and ligated to the plasmid and transformed into DH5alpha, but no positive colonies were obtained on colony PCR. We could not pursue this further due to time constraints, hence the above construct was not characterised. The other constructs that were designed by varying the strengths of RBS and promoter for this lldR + lldD gene combination were not SOEed as we could not standardise the protocols.
