Using a module exchange approach, we have tested a longstanding model for the role of Cro repressor in λ prophage induction. This epigenetic switch from lysogeny to the lytic state occurs on ...

Researchers turned programmable proteins into a novel genetic tool, potentially enabling tighter control of gene expression. LacI is a tetrameric protein, using two dimers to bind two specific, ...
