Synthetic operon designed with GerAA, GerKB and GerAC coding sequences from the B. subtilis genome. Designed to be transformed in a B. subtilis knockout strain so as to produce a germinant receptor that contains a binding site for glucose, and when activated triggers an orthogonal signalling cascade resulting in germination.  It is an improved version of the GerAK chimera.

Design Notes

PsspB is a promoter, which can aid the expression of gerA. GerA is one of the germinant receptors of B.subtilis, and it can respond to the presence of L-alanine and increase the germinantion rate of B.subtilis. However, we planned to engineer the receptor to make it more sensitive to N-acetylglucosamine (NAG) - the chitin monomer. The previous iGEM team iGEM17_SZU-China proved the superior transcription efficiency of this promoter. tL3S2P21 is a strong promoter, which helps to increase the production of desired protein. We included the operon for germinant receptor GerA because GerA is responsive to L-alanine and responsible for B.subtilis germination (Ramírez-Guadiana et al., 2017). Synthetic operon designed with GerAA, GerKB and GerAC coding sequences from the B. subtilis genome. Designed to be transformed in a B. subtilis knockout strain so as to produce a germinant receptor that contains a binding site for glucose, and when activated triggers an orthogonal signalling cascade resulting in germination. It is an improved version of the GerAK chimera.
