β-gаlаctоsidаse (LacZ) cоnverts lactоse into allolactose and eventually hydrolyzes it into simple sugars. Because the enzyme degrades its own regulator, expression levels naturally fluctuate. To circumvent this feedback loop in the laboratory, researchers use a combination of IPTG and X-gal on agar plates to monitor lacZ expression. How do these synthetic analogs experimentally bypass the natural autoregulatory loop?
