Malachite green (MG), a widely-used and recalcitrant dye, has been confirmed to be carcinogenic and mutagenic against many organisms. Herein, we were aimed at the investigation of the hypothetic role of ligninolytic bacterial enzymes similar to fungal ones in the degradation of synthetic dyes. A multiple increase in the laccases and DyP-peroxidases genes expression level was recorded by RT-qPCR for bacteria of the genus Azospirillum in the presence of MG.

5′-Ectonucleotidase (NT5E) catalyzes the conversion of adenosine monophosphate to adenosine and free phosphate. The role of this ectonucleotidase and its production of adenosine are linked with immune function, angiogenesis, and cancer. NT5E activity is typically assayed either by chromatographic quantification of substrates and products using high-performance liquid chromatography (HPLC) or by quantification of free phosphate using malachite green. These methods are not suitable for robust screening assays of NT5E activity. HPLC is not readily suitable for the rapid and efficient assay of multiple samples and malachite green is highly sensitive to the phosphate-containing buffers common in various media and sample buffers. Here the development and validation of a novel high-throughput ectonucleotidase screening assay are described, which makes use of a luciferase-based assay reagent, the Promega CellTiter-Glo kit, to measure the catabolism of AMP by NT5E. This multiwell plate-based assay facilitates the screening of potential ectonucleotidase antagonists and is unaffected by the presence of contaminating phosphate molecules present in screening samples.
