Biology
As a photoactivated diguanylate cyclase (DGC), the chimeric protein BphS consists of the N-terminal photosensitive module of the BphG protein from Rhodobacter sphaeroides and the introduction of the R587A mutation into the RXXD motif from the C-terminal GGDEF domain of Slr1143. BphS protein is activated by changes in protein conformation under NIR light irradiation, thereby synthesizing c-di-GMP.
Usage
The coding sequences for BphS and BphO were inserted into the expression vector with BBa_K880005 (BBa_J23100 &BBa_B0034) to obtain J23100-B0034-bphS-pET RBS-bphO-rrnB T1 (BBa_K3740047). 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.
