Cloned DNA: Ampicillin resistance gene (amp); signal sequence
Human tumor necrosis factor cDNA (TNF); mutated mature sequence
Promoter: Escherichia coli β-lactamase promoter (amp)
Phage λ major leftward promoter (λ PL)
binding site:
Ribosome binding site (RBS) of the Escherichia coli ampicillin resistance gene (amp)
Terminator: -
Selection marker: Ampicillin (amp)
Replicon: Escherichia coli plasmid pMB1 origin
Host range: Escherichia coli; use strains with a cI function, cIts for PL controlled expression
Parental clone: pPLc28BHTNF; pMaT4HTNFTm28F
Further information: The plasmid was constructed by inserting the AvaI-BstEII fragment of pMaT4HTNFTm28F, containing the
mutated mature hTNF sequence, into the AvaI-BstEII opened pPLc28BHTNF plasmid.
The plasmid contains the amp signal sequence, fused in frame to the mutated mature hTNF sequence.
The first 7 amino acids of the mature hTNFm28F are identical to wild type, but are encoded by the synthetic linker sequence.
Strains, containing pPLc28BHTNFm28F, secrete mature hTNFm28F into the periplasmic space, in a temperature dependent mode.
The ampicillin resistance gene does not contain a PstI restriction site.
Expresssion in λ wt lysogen : constitutive synthesis under control of the amp promoter at any physiological temperature.
Expression in cIts : λ-PL induction at 42°C.
