Genetically Encoded Initiator For Polymer Growth From Proteins
This invention pertains to methods for producing homogeneous recombinant proteins that contain polymer initiators at defined sites. The unnatural amino acid, 4-(2′-bromoisobutyramido)phenylalanine of formula 1, was designed and synthesized as a molecule comprising a functional group further comprising an initiator for an atom-transfer radical polymerization (‘ATRP”) that additionally would provide a stable linkage between the protein and growing polymer. We evolved a (Mj) tyrosyl-tRNA synthetase/tRNApair to genetically encode this unnatural amino acid in response to an amber codon. To demonstrate the utility of this functional amino acid, we produced Green Fluorescent Protein with the unnatural amino acid initiator of formula 1 site-specifically incorporated on its surface (GFP-1). Purified GFP-1 was then used as an initiator under standard ATRP conditions with oligo(ethylene oxide)monomethyl ether methacrylate, efficiently producing a polymer-GFP bioconjugate wherein the polymer is connected at a specifically selected site on GFP.

Abstract:
A three-dimensionally ordered macroporous hydrogel for immobilizing a selected bioresponsive molecule and method of making are disclosed. The three-dimensionally ordered macroporous hydrogel comprises a crosslinked polymer that has a system of interconnected pores. The interconnected pores have a uniform pore size in the range of 50 to 5000 nm, and a plurality of first pore functional groups. The plurality of first pore functional groups is selected to immobilize a selected bioresponsive molecule. Examples of bioresponsive molecules include an enzyme; a molecule for: a protein scaffold, solid phase synthesis, nucleic acid synthesis, polypeptide synthesis, analyte detection, adsorption of analytes and measuring analyte concentrations, organic synthesis, and degradation of biologically active agents in wastewater. A method includes forming a colloidal crystal template, polymerizing a hydrogel within the pores of the colloidal crystal template, and selectively removing the colloidal crystal template. The hydrogel can be polymerized using CRP, ATRP and FRP polymerization processes.

Abstract:
A method of synthesizing a polynucleotide composition includes attaching a compound including at least one initiator or at least one transfer agent for a reversible deactivation radical polymerization to an end of a nucleotide chain assembly immobilized upon a solid phase support during a solid phase synthesis of a polynucleotide so that the initiator or the transfer agent is attacked to the end of a nucleotide chain assembly in a manner which is stable under conditions of deprotection of the polynucleotide, and growing a polymer from the initiator of from a site of the chain transfer agent via the reversible deactivation radical polymerization to form the polynucleotide composition.
Atom Transfer Radical Polymerization Under Biologically Compatible Conditions
Methods for conducting controlled grafting-from radical polymerizations from biomolecules under conditions that are biologically compatible are described. The methods provide biomolecule-polymer conjugates with highly controlled structures and narrow polydispersities under aqueous reaction conditions and biological temperatures. Biomolecules, such as proteins and nucleotides can be conjugated to polymers with high levels of control.
