MerR-type regulator ZccR links zinc homeostasis to biofilm formation and interspecies competition in Streptococcus mutans
Zinc is widely present in the oral microenvironment and can influence the growth of oral bacteria. ZccR is a MerR-type transcriptional regulator that controls zinc efflux in Streptococcus mutans ( S. mutans ), but its role in biofilm virulence and interspecies competition with oral commensals remains unclear....
