rpoD sigma factor


ropD gene (BBa_K4271010), comprises N-terminal 69 amino acid for polyP binding, E. coli RpoD (1-555 a.a), C-terminal 4.2 region for UreA promoter recognition (BBa_K4271011).

The rpoD sigma factor is a factor under the sigma-70 family and is a common sequence in E. coli. Activated by polyphosphate bondage, the sigma factor will be expressed and assist the RNA polymerase to bind to downstream ureA promoter (BBa_K4271011), thus expressing the mCherry (BBa_J18932) fluorescent protein for detection to determine engineering success. The usage of the rpoD sigma factor can be seen in BBa_K4271013 and BBa_K4271014.
