High-level expression vectors to synthesize unfused proteins in Escherichia coli. 1986

A Seth, and P Lapis, and G F Vande Woude, and T Papas

A new class of plasmid vectors (pANK-12, pANH-1, and pPL2) for synthesizing unfused proteins was constructed by inserting synthetic linkers at the NdeI site (CATATG) of plasmid pJL6, which contains the lambda cII gene initiator codon. These expression vectors contain the lambda pL promoter, the cII ribosome-binding site, cII start codon and unique restriction sites (KpnI, Asp718, HpaI, BamHI) downstream from the initiator ATG for expression of unfused proteins. The main advantage of these vectors is that any DNA fragment with an open reading frame that does not possess a start and/or a stop codon can be directed to overproduce protein in an unfused form.

D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli

D005822	Genetic Vectors	DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.
