An XRE-type regulator in Streptococcus mutans plays an important role in brpA expression and oxidative stress tolerance response
ABSTRACT This study used a functional genomics approach to explore the role of a xenobiotic response element (XRE)-type regulator (SMU.405c) in Streptococcus mutans physiology, including the expression of biofilm regulatory protein BrpA. Results showed that deletional mutation of xre significantly reduced the ability o...
