The F-ATPase operon promoter of Streptococcus mutans is transcriptionally regulated in response to external pH

J Bacteriol. 2004 Dec;186(24):8524-8. doi: 10.1128/JB.186.24.8524-8528.2004.

Abstract

Streptococcus mutans F-ATPase, the major component of the acid-adaptive response of the organism, is transcriptionally upregulated at low pH. Fusions of the F-ATPase promoter to chloramphenicol acetyltransferase indicated that pH-dependent expression is still observed with a short promoter that contains a domain conserved between streptococcal ATPase operons.
