DNA-Linked Enzyme-Coupled Assay for Probing Glucosyltransferase Specificity.
ACS Synth. Biol. 4 , 833-41, (2015) Traditional enzyme characterization methods are low-throughput and therefore limit engineering efforts in synthetic biology and biotechnology. Here, we propose a DNA-linked enzyme-coupled assay (DLEnCA) to monitor enzyme reactions in a high-throughput manner.... |
