regulation of DNA operator binding in the ArsR/SmtB family of metal-sensing proteins using
computational methods. The paradigm, zinc-sensing transcriptional repressor
Staphylococcus aureus CzrA represents an excellent model system to understand how
metal sensor proteins maintain cellular metal homeostasis. Here, we discuss studies that
helped to characterize a metal ion-mediated hydrogen-bonding pathway (HBP) that plays a …
