Usage
In recent years, the marine bacteria of the genus Pseudoalteromonas has been proposed as a non-conventional expression organism for low temperatures, due to its optimal growth in cold conditions and its ability to express “easy proteins” (1). With this purpose in mind, designed expression systems have successfully produced recombinant proteins in bacteria from this genus (2-4). Consequently, our team chose elements from these expression systems previously reported, like the Pasp promoter, in order to control the expression of our protein type of interest, AFP, in Pseudoalteromonas nigrifaciens. This way, our team will use Pasp along with its RBS (this part) and the reporter GFP (BBa_K3612010) to characterize the promoter, and with that, choose the most fit promoter for expression of the AFPs in Pseudoalteromonas nigrifaciens.
Biology
The ribosome binding site of the constitutive promoter Pasp (Part number: K3612011) from Pseudoalteromonas haloplanktis TAC125 allowed the expression of alpha amylase in bacteria of Pseudoalteromonas genus (5, 6).
