JG
Miniprep J61003+Enny and Benny+J61003
Minis are in -20
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).

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

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 14
JG, MC

Extract
Transform
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 19
October 20
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.
