ML
Brought the tubes labelled "sequencing rxns" up to MBSU
Also brought some XBA 1 from fermentas freezer since we ran out
Digests JG's miniprep with Xbal and PST. Ran out of out of XBA during digests, which meant that EJ 4,5,6only digested with XBA for 35 min
Colony O/N of I0500/ J61003 and Buddy/J61003

October 2

VH-1PM
No Kan plates therefore made kan plates
On COuntertop
Miniprepped ML's overnights from OCt 1
Lysis solution is a no go
Started new O/N of previows overnights for tomorrow
No more LB

WM is Wayne Materi (a team advisor) in the following.

WM- Assembling all the individual genes into an operon in order of their role in the butanoate pathway from KEGG. We will start with I725021 (RBS + B-hydroxy butyryl coA dehydrogenase in the B0034 plasmid - pSB1A2)then insert I725022 (RBS + Enoyl-coa hydratase), then I725023 (RBS + Butyryl coa Dehydrogenase), then I725024 (RBS + Butyraldehyde dehydrogenase), and finally I725025 (RBS + Butanol dehydrogenase). After the operon is constructed and verified, we will insert the Arabinose promoter from I0500 5' to all the genes.

Digest I725021/SpeI+PstI and gel purify ~3kb band Digest I725022/SpeI+PstI and gel purify ~1.2kb band

Ligate (Got 16 colonies vs. 10 for negative ctl).

         I725023/XbaI+PstI (gel purify ~850bp band - already have)

Cutout, bands, quantitated DNA and ligated -> Plate 150 ul on LB+Amp

ED 9:00

NG 12:00

WM - did 8 O/Ns and minipreps

Verify with XbaI+SpeI digest (expect 2149+2916bp bands if good)

All but 4 and 8 look good. Sequence BuOP2.1, 2.2, 2.5, 2.6 with Primer 2

         I725024/XbaI+PstI (expect 2149bp and 2642bp - gel purify larger band)Not shown

Cutout all four bands and gel purify. I725024 was digested and gel-purified seperately. Quantitation of bands showed ~5pmol/ul for BuOP2/SpeI+PstI digests and ~7pmol/ul for I725024/XbaI+PstI digests.

Ligations (fast tracking construction). Plate 150ul on LB+Amp

JP?
PCR thiolase
Transformed Buddy in Boo 1+2 into competentent cells, plated on AMP+ plates

WM - Do Colony PCR on 7 colonies (from very few transformants) with Primer 4 and VR (expect ~240bp if good).

Didn't work very well. Try confirming by digest.

October 12

MC, JG @ 800hrs
Ran gel of PCR products
No growth on the buddy in Boo transformation
Religations of buddy into boo but couldnt find Buddy therefore religations halted

WM - Verify BuOP3 by digest with XbaI+SpeI (expect 2.1 and 5.6kb bands if good)

Sequence 1, 4, 5, 6 with Primer 3 to confirm

October 13

ML
Religated buddy and Boo
Note: when free of tasks work on poster, or presentation or wiki or call justin or erin

WM - BuOP3.4 and 3.5 sequenced good. Due to time considerations we will call BuOP3.4 part I725099 and submit this.

October 16

NK- Digested B0034 with Spe and PST.

-Ran a gel of restriction

-Extracted Thiolase from gel on previous day.

VH and AL - Took a picture of gel

-Cut out and purified four bands of B0034 from previous digestion

JP- Ligate B0034 with Buddy

WM - Verifying I725025 a.k.a. Buddy in Boo) The ligation and transformation already seem to have been done and produced many colonies. So I will do colony PCR with Primer 5 and VR (expect 250 bp) to confirm.

All 16 colonies tested look good. Setup 12 O/Ns to verify by digest.

October 17

WM verify I725025 by /XbaI+SpeI digest (expect 2149+1.2kb bands)

All looked good. Sequence 1, 2, 9, 10.

October 18

VH - Transformed B0034, Buddy ligations from yesterday and plated them on Amp plates

WM - I725025 sequences all good. Use #1.

October 21

October 22

I'll be there at 3-NK

ML - Gel purified Boo-Thiolase

-Digested B0034 with ECO and PST

-Ligated Thiolase with B0034

WM - Add arabinose promoter in front of individual genes so that each protein can be seperately expressed and purified using the His-tags we introduced.

Arabinose promoter (+AraC repressor) comes frmo I0500.

Digests:

        I725021/EcoRI+XbaI
        I725022/EcoRI+XbaI
        I725023/EcoRI+XbaI
        I725024/EcoRI+XbaI
        I725025/EcoRI+XbaI
        I0500/EcoRI+SpeI

Note: I0500 concentration is quite low. Probably need to grow it up O/N then induce O/N with IPTG after that.

Setup ligations anyway.

October 23

AL and NK - Transformed B0034 and Thiolase into XL10 Gold Cells.

WM - very few colonies from ligation Did 1 O/N from each kind of ligation/transformation for digest verification.

October 24

WM - Digest O/Ns of arabinose + individual genes for I725021, 022, 024, 025 Digest with /XbaI+SpeI

Expected sizes (in addition to common 2149bp band):

          I725021 - 2100bp
          I725022 - 2400bp
          I725024 - 3839bp
          I725025 - 2435bp

First and last ligation looked like they worked. We will try to do this again.

October 25
