Making the Mtd Biobrick

To create this biobrick, we utilized a combination of splicing overlap extension PCR and Gibson Assembly to extract a sequence from the BPP-1 phage's genomic DNA that would be free of the standard biobrick restriction enzyme sites. The protocols for those methods are listed below:

PCR to generate fragments of mtd

In this step, four separate fragments of the mtd gene are created via PCR. This step is necessary to eliminate illegal internal biobrick sites (EcoRI, PstI, NotI) and to add necessary biobrick sites to the 5' and 3' ends.

4CCAACACTGGAGGCCGCGGATCGG AAGGCTGCAGCGGCCGCTACTAGTCTCAAGAATCAGG


The 20 µL PCR mix for each fragment is as follows:

ReagentVolume
mtd genomic template1.0 µL (4.5 ng total)
10 µM forward primer1.0 µL
10 µM reverse primer1.0 µL
10 mM dNTPs0.4 µL
Buffer HF4.0 µL
Phusion Polymerase0.2 µL
ddH2O12.4 µL


The thermocycler program for each reaction is as follows:

# CyclesTemperature (°C)Time

Variable (70 for fragment 1, 69 for fragment 2, 69 for fragment 3, 72 for fragment 3)

The PCR product is then resolved on a 1% agarose gel and excised and column-extracted.

Splicing Overlap-Extension (SOE) PCR to connect fragments 3 and 4

The 20 µL reaction mix is as follows:

ReagentVolume or Mass
Fragment 320 ng total

10 mM dNTPs0.4 µL

Gibson Assembly of Fragments 1,2, and 3-4

The mix for the Gibson Assembly is as follows:

ReagentConcentration or Volume
Fragment 10.2 pM
Fragment 20.2 pM
Fragment 3-40.2 pM
Assembly Master Mix (from New England Biolabs)fill to 5.0 µL

The mix is then incubated at 50 °C for 1 hour.


PCR amplification of mtd

The mix for the amplification is as follows:

ReagentVolume or Mass
mtd20 ng
10 µM forward primer (CCTTGAATTCGCGGCCGCATCTAGAATGAGTACCGCAGTCCAGTTCCG )0.6 µL
10 µM reverse primer (AAGGCTGCAGCGGCCGCTACTAGTCTCAAGAATCAGG )0.6 µL
10 mM dNTPs0.4 µL
2x xtreme buffer10 µL
KOD xtreme hot start polymerase0.4 µL
ddH2Ofill to 20 µL

The thermocycler program for the amplification is as follows:
