摘要
In a new, versatile approach to functionalizing recombinant spider silk, L-azidohomoalanine is introduced residue-specifically in the minispidroin protein 4RepCT through expression in an E. coli methionine auxotroph. Both fluorophores and the antibiotic levofloxacin are attached to this bio-orthogonal amino acid using copper-catalyzed click chemistry, either before or after the silk fibers are self-assembled.
