Plasmid cloning vectors for gene therapy with phosphohistidine-based oligos


Artificial DNA primers: phosphoramidate-based oligonucleotide synthesis


  • N-6-benzoyl-deoxyadenosine phosphoramidite - Notice the P-N bound indicating the linkage of a phosphonate diester to a benzoyl atom :)
  • N-3-oxo-hexanoyl-L-homoserine lactone - A light-inducible phosphohistidine-bound AHL ? A(denosine)TP/cAMP dependent.
  • Reminder:
    • NHC = (N heterocycle carbene) - Chemical compounds with a N chiral prodrug switch - highly enantioselective molecules
    • N = indicates a Nitrogen atom
    • P = a Phosphonate (inorganic state) - a compound for oligo synthesis using the nucleoside phosphoramidite method.
    • P-N = phosphoramidate (a Nitrogen atom bound to a Phosphonate ester in nucleophilic substitution).

deoxynucleotide synthesis:

  • cDNA synthesis building block = deoxynucleoside + 3'-phosphonate = synthetic nucleotide analog (dATP) 1

oligodeoxyribonucleotide synthesis:

  • short 50-200(?) bp restriction endonucleases enzymes for cDNA catalysis/plasmid vector cloning in E. coli
  • building blocks for oligonucleotides synthesis with phosphoramidites method 1
  • see also Oligonucleotide Synthesis

M13K07 cloning in E. coli:

  • amino-acid sequence signature (Myc epitope tag) = EQKLISEEDL
