We previously reported that the systematically mined β-glucosidase from Shinorhizobium meliloti efficiently converted the indican or plant extracts (containing the natural indican) of Polygonum tinctorium into a bright blue pigment indigo. The β-glucosidase was determined to be a monomer with a calculated molecular mass of 52 kDa, and also expressed at high level in soluble fraction under the control of novel expression system equipped with a selected promoter from metagenome. Subsequently, we develop a sensitive reporter system for gene cloning, which was suitable for discriminating the recombinant clones from negative ones in a high throughput manner. Using the novel chromogenic substrate indican, we analyzed the reporter system in terms of sensitivity, reliability and reproducibility. In addition, the Shinorhizobium β-glucosidase was also readily hydrolyzed the fluoregenic substrate MUG(4-Methylumbeliferyl-β-D-glucopyranoside) and a typical chromogenic X-gal, thereby providing a possibility that our system was broadly applied to various fields of molecular biology and bioengineering.
