Part:BBa_K5043011
amilGFP transcriptional unit
This part is a transcriptional unit, coding for amilGFP using Anderson promoter J23110, standard RBS B0034 and Terminator Luz7-T50. It was designed to verify protein production in Pseudomonas species.
Usage and Biology
Pseudomonas putida KT2440 [1] as well as Pseudomonas vancouverensis DSM8368 [2] show promising abilities as chassis for bioremediation of organic pollutants. [3, 4] In this context, we were interested in a low/medium constitutive expression system working in both bacteria. Hence, we decided to use Anderson promoter J23110, as it leads to medium expression in P. putida KT2440. [5] In addition, we chose RBS B0034 and Terminator Luz7-T50 both showing good efficiency in P. putida KT2440. [6, 7] As we could not find literature about these regulatory elements’ function in P. vancouverensis, amilGFP was used as reporter protein for qualitive assessment of protein production using this expression system. For this purpose, the shown composite part was cloned into pSEVA231-backbone. [8] Pseudomonas species were transformed using electroporatoration. Cell pellets of transformed liquid cultures exhibited no visible green colour under daylight, but green fluorescence under blue light.
As visible in the pictures, bacterial cultures bearing this composite part show green fluorescence, indicating GFP production. Thus, promoter J23110 and RBS B0034 both function in both P. putida KT2440 and P. vancouverensis DSM8368. The expression system is working.
