Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 96-13-9, is researched, Molecular C3H6Br2O, about A paper-based whole-cell screening assay for directed evolution-driven enzyme engineering, the main research direction is halohydrin dehalogenase whole cell screening assay evolution; Directed evolution; Halohydrin dehalogenase; Library screening; Paper-based assay; Smartphone imaging.SDS of cas: 96-13-9.
However, the need for a large reagent volume and sophisticated instrumentation hampers its broad implementation. In an attempt to address this problem, here we report a paper-based high-throughput screening approach that should find broad application in generating desired enzymes. As an example case, the dehalogenation reaction of the halohydrin dehalogenase was adopted for assay development. In addition to visual detection, quant. measurements were performed by measuring the color intensity of an image that was photographed by a smartphone and processed using ImageJ free software. The proposed method was first validated using a gold standard method and then applied to mutagenesis library screening with reduced consumption of reagents (i.e., = 10μl per assay) and a shorter assay time. We identified two active mutants (P135A and G137A) with improved activities toward four tested substrates. The assay not only consumes less reagents but also eliminates the need for expensive instrumentation. The proposed method demonstrates the potential of paper-based whole-cell screening coupled with digital image colorimetry as a promising approach for the discovery of industrially important enzymes. Key Points · A frugal method was developed for directed enzyme evolution. · Mutagenesis libraries were successfully screened on a paper platform. · Smartphone imaging was efficiently used to measure enzyme activities.
