abstract

• Rapid, sensitive, and sequence-specific DNA detection can be achieved in one step using an engineered intrasterically regulated enzyme. The semi-synthetic inhibitor-DNA-enzyme (IDE) construct (left) rests in the inactive state but upon exposure to a complementary DNA sequence undergoes a DNA hybridization-triggered allosteric enzyme activation (right). The ensuing rapid substrate turnover provides the built-in signal amplification mechanism for detecting approximately 10 fmol DNA in less than 3 min under physiological conditions.
