E. Coli

Pyruvate Decarboxylase & Alcohol Dehydrogenase

JC: To insert PDC/ADH genes into the σ70 constitutive promoter plasmid, 0.5ug of σ70/pSB1A3 (2190bp) was digested with SpeI and PstI and 0.5ug of PDC/ADH/pSB1C3 (5124bp) was digested with XbaI and PstI. These digestions cut out the red fluorescent protein (rfp) tag on pSB1A3 (rfp=885bp) to aid in colony selection. Digestions were run on a 1% agarose gel, and bands obtained confirmed PDC/ADH (3054bp), pSB1C3 (2070bp), σ70/pSB1A3 (2190), and rfp (885bp). Incomplete digestion of PDC/ADH/pSB1C3 was apparent for sample #8, so the sample was re-digested before ligation.

PDC/ADH-XbaI/PstI and σ70/pSB1A3-SpeI/PstI were ligated and transformed into NEB10 β cells. Single colonies from LB-Ampicillin plates were selected and tested on LB-Amp and LB-Chlor plates. No usable colonies were obtained (all were light pink and grew on both LB-Chl and LB-Amp plates).=(

E. Coli

Pyruvate Decarboxylase & Alcohol Dehydrogenase

PDC/ADH was re-digested with XbaI/PstI and run on a 1% agarose gel to confirm digestion. Bands obtained confirmed PDC/ADH (3054bp), and pSB1C3 (2070bp). PDC/ADH-XbaI/PstI and σ70/pSB1A3-SpeI/PstI were re-ligated and transformed into NEB10 β cells.

To isolate PDC/ADH genes with the σ70 constitutive promoter, 0.5ug of PDC/ADH/σ70/pSB1A3 was digested with EcoRI and PstI. Digests were run on a 1% agarose gel, and bands confirmed σ70/PDC/ADH (3089bp) and pSB1A3 (2155bp).
