GAL promoter
Inducible promoter region of the yeast operon that encodes, among other things, the enzyme beta-galactosidase. Extensively used, as is the prokaryotic analogue, because the blue colour generated by the action of the enzyme on Xgal is a convenient marker of colonies containing the vector. The transcription factor that binds to the promoter (GAL4) is much used in yeast two-hybrid screening.
