title: Enzyme annotation with chemical tools.
abstract: Defining the activity of an enzyme in a cell-based system is preferable to in vitro biochemical techniques requiring extensive purification. Chiang et al. use small molecules, RNA interference, and metabolomics to characterize a novel enzyme upregulated in cancer cells.
