{ "DOI": "10.1021/acs.macromol.5b02323", "abstract": "Tetrazine end-functionalized telechelic polymers were synthesized by controlled radical polymerization (CRP) and employed to generate T4 lysozyme homodimers. Mutant T4 lysozyme (V131C), containing a single surface-exposed cysteine, was modified with a protein-reactive trans-cyclooctene (T4L-TCO). Reversible addition-fragmentation chain transfer (RAFT) polymerization yielded poly(N-isopropylacrylamide) (pNIPAAm) with a number-average molecular weight (Mn by 1H NMR) of 2.0 kDa and a dispersity (D by GPC) of 1.05. pNIPAAm was then modified at both ends by postpolymerization with 6-methyltetrazine. For comparison, 2.0 kDa bis-tetrazine poly(ethylene glycol) (PEG) and 2.0 kDa bis-maleimide pNIPAAm were synthesized. Ligation of T4L-TCO to bis-tetrazine pNIPAAm or bis-tetrazine PEG resulted in protein homodimer in 38% yield and 37% yield, respectively, after only 1 h, whereas bis-maleimide pNIPAAm resulted in only 5% yield of dimer after 24 h. This work illustrates the advantage of employing tetrazine ligation over maleimide thiol-ene chemistry for the synthesis of protein homodimer conjugates.", "author": [ { "family": "Lorenzo", "given": " Maltish M." }, { "family": "Decker", "given": " Caitlin G." }, { "family": "Kahveci", "given": " Muhammet U." }, { "family": "Paluck", "given": " Samantha J." }, { "family": "Maynard", "given": " Heather D." } ], "container_title": "MACROMOLECULES", "id": "53991", "issue": "1", "issued": { "date-parts": [ [ 2016, 1, 1 ] ] }, "page": "30-37", "title": "Homodimeric Protein-Polymer Conjugates via the Tetrazine-trans-Cyclooctene Ligation", "type": "article-journal", "volume": "49" }
