synthesis and semi synthesis of proteins

Transcript of synthesis and semi synthesis of proteins

  • Protein Engineering

    BIT317 Class 2438

    Lecture 7Synthesis and Semi-synthesis of Peptides

  • Strategy inSolid Phase Peptide Synthesis

    Pioneered byMerrifield

  • Microwave Assisted Synthesis

    Reduction in synthesis timeFor peptides that contain beta sheet structures / sterically hindered couplings

  • Major Limitation of SPPS

    Feasibility for application for larger proteins

    Higher probability of misfolding

    Enhanced error rates

    Levels of purity

    Formation of disulfide bonds (disulfide scrambling)

  • Protein semisynthesis protein ligation

  • Chemoselective ligation for artificial backbone
