Backbone

  • Vector backbone
    pKK223-3
  • Backbone manufacturer
    Pharmacia
  • Backbone size w/o insert (bp) 4300
  • Modifications to backbone
    pKD is derived from pKK223-3 (Pharmacia). The ampicillin (Amp) resistance gene was replaced with a kanamycin (Kan) resistance gene. The original multiple cloning site (MCS; NcoI-EcoRI-SacI) was modified by adding an additional ribosome binding site (RBS) and a second MCS (NdeI-BamHI-SalI-HindIII), thus enabling simultaneous protein expression from two genes, both under the control of the same tac promoter.

Depositor Comments

To prevent possible enzymatic dephosphorylation of O-phospho-L-serine (Sep) in vivo, the gene encoding phosphoserine phosphatase (serB), which is catalyzing the last step in serine biosynthesis, was deleted from Escherichia coli strains Top10 (Top10∆serB - Addgene #34928) and BL21 (BL21∆serB - Addgene #34929). These strains are required hosts when using this plasmid.

Certain elements of this plasmid are covered under US patent 9,090,928 to Yale University
