Part:BBa_K1846001

Bacteriophage lambda tail fibre assembly protein circuit

This part provides the gene sequence for tfa (tail fibre assembly) protein, 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).

Usage and Biology

The tfa (tail fibre assembly) protein of bacteriophage lambda assists in the assembly of the stf (short tail fibre) protein into a functional short tail fibre [1],[2]. Tfa gene displays a high level of homology (~40%) with the gp38 of bacteriophage T4 [2],[3],[4].
