(= b-galactosidase)
Enzyme (EC encoded by the LacZ gene, that is widely used as a reporter gene, as a variety of coloured or fluorescent compounds can be produced from appropriate substrates (typically Xgal, that produces a blue colour). LacZ is incorporated in many plasmid vectors to allow blue-white colour selection.
