[http://partsregistry.org/Part:BBa_K358000 BBa_K358000]: Lac promoter with GFP

The lac promoter will be repressed and not induce GFP in the presence of lacI. We measured the strength of fluorescence with low copy plasmid vector, [http://partsregistry.org/Part:pSB4K5 pSB4K5].

[http://partsregistry.org/Part:BBa_K358001 BBa_K358001]: Measurement Standard

Constitutive promoter [http://partsregistry.org/Part:BBa_J23101 BBa_J23101] with GFP on low plasmid [http://partsregistry.org/Part:pSB4K5 pSB4K5].

[http://partsregistry.org/Part:BBa_K358004 BBa_K358004]: lambda lysis cassette[SRRz/Rz1]

This part causes cell death. It contains Holin/Antiholin, Endolysin and Rz/Rz1 genes.

[http://partsregistry.org/Part:BBa_K358006 BBa_K358006]: lambda lysis cassette with terminator

λ lysis cassette [http://partsregistry.org/Part:BBa_K358004 BBa_K358004] with double terminator [http://partsregistry.org/Part:BBa_B0015 BBa_B0015].

[http://partsregistry.org/Part:BBa_K358010 BBa_K358010]: anti-killer gene with GFP

It codes S_ΔTMD1 as the anti-killer gene, which is derived from λ phage DNA and against the lambda lysis cassette [http://partsregistry.org/Part:BBa_K358005 BBa_K358005]: the killer gene.

[http://partsregistry.org/Part:BBa_K358012 BBa_K358012]: S_ΔTMD1

S gene, which is derived from lambda phage DNA, contains holin and antiholin. These proteins have three transmembrane domains. This S_ΔTMD1, however, lacks one of those domains and works as the anti-killergene against the lysis cassette, killer gene.

[http://partsregistry.org/Part:BBa_K358013 BBa_K358013]: S_ΔTMD1 with terminator

S_ΔTMD1 with double terminator.

[http://partsregistry.org/Part:BBa_K358015 BBa_K358015]: pLac+anti-killer gene

The anti-killer gene with GFP [http://partsregistry.org/Part:BBa_K358010 BBa_K358010] is expressed under the control of lac promoter.

[http://partsregistry.org/Part:BBa_K358016 BBa_K358016]: pLac+anti-killer gene+pConst

pLac+anti-killergene+pConst.

[http://partsregistry.org/Part:BBa_K358017 BBa_K358017]: low promoter+anti-killer gene

Low constitutive promoter [J23105] and anti-killer gene [http://partsregistry.org/Part:BBa_K358010 BBa_K358010].

[http://partsregistry.org/Part:BBa_K358018 BBa_K358018]: Low promoter+anti-killergene+lacP

Constitutive promoter [http://partsregistry.org/Part:BBa_J23105 BBa_J23105] + anti-killergene [http://partsregistry.org/Part:BBa_358010 BBa_358010] + lactose promoter [http://partsregistry.org/Part:BBa_R0011 BBa_R0011].

[http://partsregistry.org/Part:BBa_K358019 BBa_K358019]: Lysis cassette regulated by lacP

Lysis cassette[SRRz] is regulated by lactose promoter. Activating lactose promoter and expressing SRRz gene, it causes the cell lysis. So, lactose promoter must be repressed when transform this part.

To repress lactose promoter tightly, we constructed this part on low copy plasmid, pSB4K5, and transformed into KRX, not TOP10. KRX has lacI in its genome and TOP10 hasn't (see genotype [http://www.promega.com/pnotes/94/14410_27/14410_27.pdf], [http://openwetware.org/wiki/E._coli_genotypes#TOP10_.28Invitrogen.29]).

[http://partsregistry.org/Part:BBa_K358020 BBa_K358020]: Lysisbox

This part consists two module. Constantly expressed killer gene [http://partsregistry.org/Part:BBa_K358004 BBa_K358004] by low promoter and regulatory expressed anti-killer gene with GFP by lac promoter.

[http://partsregistry.org/Part:BBa_K358021 BBa_K358021]: Lysisbox -module2-

Anti-killergene is induced constitutively and killergene is regulated by lactose promoter.

[http://partsregistry.org/Part:BBa_K358022 BBa_K358022]: lacP + SΔTMD1RRz

TMD1 is deleted from lysis cassette [SRRz].

[http://partsregistry.org/Part:BBa_K358023 BBa_K358023]: Lysisbox ver.2

This part is the same to BBa_K358020[Lysisbox], except for its constitutive promoter[BBa_J23100]. So, this plasmid is able to induce the killer gene more than the plasmid contains BBa_K358020. This part also contains SΔTMD1, anti-killergene, regulated by lacP. When transform this part, you must induce the SΔTMD1 highly, do not repress lacP, so that the cell lysis will be prevented. This is a long part and a lactose operon was deleted sometimes unexpectedly in our experiments. So, we recomend you that it is better to set the cultural temperature at 30C and store this part as a plasmid, not a glycerole stock.

[http://partsregistry.org/Part:BBa_K358024 BBa_K358024]: Lysisbox -module2- ver2

This part is the same to BBa_K358021[Lysisbox -module2-], except for its constitutive promoter[BBa_J23101]. So, this part also induces constitutively SΔTMD1 gene, the anti-killer gene, and lambda lysis cassette[SRRz], the killer gene, is regulated by lacP. Since the lysis cassette is toxic to E.coli, you must repress the lacP when you transform it. Because of this, Top 10 isn't suitable, we used KRX. This is a long part and a lactose operon was sometimes deleted unexpectedly in our experiments. So, we find that to set the cultural temperature at 30C and store this part as a plasmid, not a glycerol stock, is the prefareble.
