Description
The Bacillus megaterium pPT7 cloning vector is part of the T7 RNA Polymerase high yield gene expression system for Bacillus megaterium.
About the T7 RNA polymerase expression system
The Bacillus megaterium high yield T7 gene expression system combines the features of the B. megaterium system in E. coli with the T7 RNA polymerase expression system regulation by the xylose operon.
This dual plasmid system is based on two parallel-replicating plasmids: pT7-RNAP and pPT7. pT7-RNAP contains the genes for ampicillin and chloramphenicol resistance for easy selection in E. coli (AmpR) and B. megaterium (CmR), in addition to the t7 rnap gene under control of the strong xylA promoter. pPT7 is responsible for the T7 RNAP-dependent expression of the target gene. Downstream of the T7 promoter, it comprises a multiple cloning site with ten unique restriction enzyme cleaving sites. Additionally, pPT7 comprises two resistances against ampicillin (in E. coli) and tetracycline (in B. megaterium).
B. megaterium has proven to be an excellent host for the expression of non-homologous DNA. Unlike other bacilli strains, none of the alkaline proteases are present and no endotoxins are found in the cell wall. B. megaterium can stably maintain several extra-chromosomal DNA elements in parallel. Protein yields are exceptionally high, even if inexpensive substrates are used.
