Expression, purification, and characterization of a metagenomic thioesterase from activated sludge involved in the degradation of acylCoA-derivatives.

Metagenomic libraries are a novel and powerful approach to seek for pathways involved in xenobiotic degradation, since this technique abolishes the need for cultivating microorganisms that otherwise would be overlooked if they cannot grow on standard laboratory media and conditions. In this paper, we describe the expression, purification and characterization of a novel metagenomic thioesterase which was described to be involved in phenylacetic acid degradation (A.
