DNA Minor Groove

The DNA minor groove is a structural feature of the double helix where the two sugar-phosphate backbones are closer together, creating a narrower and shallower channel compared to the major groove. This groove plays a critical role in molecular recognition, as it provides a unique chemical environment for interactions with proteins, small molecules, and ions. Targeting the minor groove can influence chromatin structure and affect accessibility for transcription factors or polymerases, making it an important target for drugs aiming to regulate gene expression or disrupt pathogenic processes involving aberrant protein-DNA interactions.
