Biology

This is a generator of fcsR (BBa_K3740022), that is used to regulate the level of c-di-GMP.

Usage

The coding sequences for FcsR were inserted into the expression vector with BBa_K880005 (BBa_J23100 & BBa_B0034) to obtain J23100-B0034-fcsR-rrnB T1 (BBa_K3740062). We introduced the constructed plasmid into E. coli DH5α to verify its successful construction, and then transferred it into G. hansenii ATCC 53582 to verify its function.

Characterization

1. Identification

As shown in Figure 2, the generator was identified successfully by PCR amplification.

2. Characterization

As shown in Figure 3, BC production in J23100-B0034-fcsR-rrnB T1-pSEVA331-G. hansenii ATCC 53582 was lower than the control group pSEVA331-G. hansenii ATCC 53582, indicating that FcsR was capable of hydrolyzing c-di-GMP in G. hansenii.
