PCR/primers

HO+pcyA, P3 vector w/o GFP

Primers were designed to PCR out the heme oxygenase and pcyA coding regions from the UT Austin plasmids. Due to the RE sites in these nonBB plasmids, their ends are given ApaLI and KpnI sites. The same is done for the P3 vector (the primers are such that we can PCR out the backbone, along with the RBS and terminator. The "P3-GFP" primers should also work for P1. However, I'm a little concerned, b/c the annotation of the P1 and P3 vectors disagrees with the sequence given for the RBS and terminator subparts.

mtrB

The same thing was done for mtrB (as for HO+pcyA). This gives us constitutive mtrB for testing the complement.

7/17: PCR

The primers arrived today, so PCR was performed using a colony of Shewanella Δ EnvZ (which should still have mtrB).
Rx mix: 90μL PCR supermix, 2μL mtrB-ApaLI-F primer (20μM), 2μL mtrB-KpnI-R (20μM), swirl of colony

PCR failed- perhaps annealing temperature was too high or too many cells. Will retry.

Rx mix (split into 12 samples): 180μL PCR supermix, 4μL mtrB-ApaLI-F primer (20μM), 4μL mtrB-KpnI-R (20μM), swirl of WT Shewanella colony, 12μL water

RE digests 07/15

We digested P53/54 with ES and P58/59 with EX. We intend to ligate these parts together. This will give us RBS + TetR/LacI + terminator + pTet/pLac + RBS + GFP + terminator.

We also digested P90 with SP and P48/P49 with XP. This will give us the CDF origin in a p15A vector with an Amp or Cm resistance cassette.

We followed the standard digest protocol under the "General Protocols" section.

RE digests 07/16

• P63, P76 (A, B, C, D), P91 (A, B, C) with EX
• P90 (α, β) with SP
• P48, P49 (A, B, C) with XP

We used the standard digestion protocol.

We plan to ligate

• P90 with P48/P49. This will give us the CDF origin in the P1 vector with Amp and Cm resistance cassettes. We will also add P63, a terminator, and the high and low constitutive promoters (P38 and P39) later.
• P91/P76 with the high and low constitutive promoters. This should give us the entire Lac and Tet plasmids.

Thermoinducible Lac System

Grew up cultures of P84 (Lac mut265) and P85 (Lac mut 241) according to protocol derived from [Chao et al. 2002] and [Yabuta et al. 1995]

Testing Thermoinducible Cultures 7/14

1. Grow up 10mL culture overnight with antibiotic at 200 RPM, 37 degrees.
2. Dilute 2.5mL of overnight culture into 50mL of fresh LB.
3. Grow at 200 RPM, 30 degrees until OD660 = 0.2.
4. Split culture into two 25mL cultures, and put one in 30 degrees and the other in 40 degrees.
5. Grow for 4 hours at these separate temperatures at 200 RPM.
6. OD and measure YFP fluorescence (Ex: 514, Em: 527).

Transformation of P75 and P92-3 (from 3x Cut) into S1 7/17

Used S1 cells frozen for electroporation.

Plasmid/ Sample	Vol DNA Added (250-300 ng DNA)	Marker	Plate After O/N incubation at 30 (7/18)	Plate Description after TWO days incubation at 30 (7/19)
P75a	3 uL	Kan	2 white colonies, ~1 mm diam. Fluorescent	4 pink/ yellow colonies (4mm), ~20 white/cream colonies, 1mm
P75b	3 uL	Kan	2 white colonies, ~1 mm diam. Fluorescent.	4 pink/ yellow colonies (4mm), ~30 white/cream colonies, 1mm
P93 1:3	2 uL	Kan	~6 white, 1mm colonies, dimmish under scope*	8 pink/yellow colonies (4mm), ~120 white/cream colonies, 1mm
P58b (miniprepped from S1)	5 uL	Kan	0 colonies	~250 white/ cream colonies, 1mm
(+) ctrl (S1 P59b)	3 uL	Kan	>100 white, 1mm colonies	120 pink/yellow colonies (4mm), ~10 white/ cream colonies, 1mm
(-) ctrl	None added	Kan	0 colonies	~20 white/ cream colonies, 1mm

1mm white/ cream colonies present on all plates after the 2 day incubation resemble the contamination we have observed in other E. coli plates. This is of interest because Kan is not as vulnerable to degradation as Carb/ Amp are.

P75a and P75b were both very bright in S1. Thermoinducible cI857 was ordered from [ATCC].

The plates of P84-5 originally transformed in E. coli from the registry were used as a standard for fluorescence for the thermoinducible Lac colonies. They were left overnight at 37°C to stimulate thermosensitivity, which should lead to YFP expression. Although they were not very bright, they glowed. Compared to these plates, the P93 1:3 transformed in S1 was noticeably dimmer, though it had been incubated at 30°C O/N. Plate will be restreaked and grown at different temperatures after the weekend.

Overnight cultures 07/18

We made overnight cultures of the parts we got from MIT

• P96
• P95
• P51
• P52
• P17

We also made cultures for plasmids we will need later

• P1 (A and B)
• P3 (A and B)
• P46 (A and B)
• P63 (A and B)
• P48
• P49 (a and B)
• P63 (A and B)

We are not completely sure if the LB Kan we used contains Kan or if it is just plain LB. So we also made a culture of P95, which is Amp resistant, in the this medium. So if it doesn't grow, then Kan was added to that bottle of LB.

07/19: All of these cultures grew except for P46A. The LB Kan really does have Kan.

• P17, P51, P52 (QPIs) with EX so we can add high/low constitutive promoters
• P63 (terminator) with EX
• P48, P49a, P49B (Amp, Cm resistance cassettes) with XP so we can add them to P90 (P1 + CDF)

Transformation of P86, P87, P97

We transformed each of the UTAustin plasmids (individually) and a new strong RBS into TOP 10 cells. The RBS has been miniprepped. The UTA plasmid transformants formed a lawn, so were restreaked first. Liquid cultures have been grown up. P87 requires mutagenesis to remove a PstI site ~100 bp into the coding region of the Cph/EnvZ fusion.
