Soluble enzymes have the unique ability to assist the conversion of complex substrates in fewer steps compared to conventional chemical synthesis; however, when immobilized to a surface, the insoluble enzyme's activity and stability can suffer in its new environment. To improve upon future immobilized enzyme efficacy, a fundamental understanding of the interactions across the enzyme, linker, and surface during covalent, site-specific immobilization that can be detrimental to its activity is required. More specifically, using a well-characterized and model enzyme, T4 lysozyme (T4L), 28 different cysteine attachment points' effects on site-specifically immobilized activity are examined. Different combinations of heterobifunctional amine-to-sulfhydryl crosslinkers …
