Abstract in brief
- The study presents a new X-ray crystal structure of the CsoR copper metalloregulator from Streptomyces lividans, revealing how it changes shape (conformational switching) when binding copper(I) ions.
- The switching mechanism involves a concertina effect at the end of specific helices in the protein, causing key residues like Cys104 to move into a position where they can bind copper, leading to structural rearrangements.
- This conformational change also alters the electrostatic surface of the protein, particularly on the DNA-binding face, which explains how copper binding causes CsoR to disassemble from DNA, triggering a genetic response to copper stress.]
