TFA (tail fibre assembly) gene circuit (BBa_K1846001)

The tfa (tail fibre assembly) protein of bacteriophage Lambda assists in the assembly of the stf (short tail fibre) protein into a functional tail fibre. This part provides the gene sequence for tfa, together with a TetR repressible promoter (TetO, available separately as BioBrick part BBa_R0040), ribosome binding site (available separately as part BBa_B0034) and an rrNB T1 terminator (available separately as BioBrick part BBa_B0010). Presence of the gene in shipping backbone pSB1C3 was confirmed by restriction with enzymes EcoRV and PstI (Fig. 1) and by Sanger sequencing.

TetR circuit (BBa_K1846003)

This is a constitutive part creating a circuit for the production of the tetracyline repressor TetR, using a constitutive, medium-copy chloramphenicol promoter (BBa_I14033), ribosome binding sequence (BBa_B0031) and double terminator (rrnb T1 terminator followed by a T7Te terminator).

Correct cloning of the part into the pSB1C3 shipping vector was confirmed by Sanger sequencing.
