This paper introduces quPCR, a calibrator-free method for absolute nucleic acid quantification by defining an intrinsic quantal unit based on replication system properties.

The paper identifies a widespread cytochrome P422 enzyme family that performs four novel tryptophan transformations, revealing new enzymatic capabilities and introducing a computational tool for HBP discovery.

This paper identifies a reductive uric acid degradation pathway in E. coli and demonstrates its therapeutic potential in reducing uric acid levels in mice.
