Abstract |
The release of phosphate from inorganic and organic phosphorus compounds can be mediated enzymatically. Phosphate-releasing enzymes, comprising acid and alkaline phosphatases, are recognized as useful biocatalysts in applications such as plant and animal nutrition, bioremediation and diagnostic analysis. Metagenomic approaches provide access to novel phosphatase-encoding genes. Here, we describe a function-based screening approach for rapid identification of genes conferring phosphatase activity from small-insert and large-insert metagenomic libraries derived from various environments. This approach bears the potential for discovery of entirely novel phosphatase families or subfamilies and members of known enzyme classes hydrolyzing phosphomonoester bonds such as phytases. In addition, we provide a strategy for efficient heterologous phosphatase gene expression. |
