Abstract

ABSTRACT A CadDX system that confers resistance to Cd 2+ and Zn 2+ was identified in Streptococcus salivarius 57.I. Unlike with other CadDX systems, the expression of the cad promoter was negatively regulated by CadX, and the repression was inducible by Cd 2+ and Zn 2+ , similar to what was found for CadCA systems. The lower G+C content of the S. salivarius cadDX genes suggests acquisition by horizontal gene transfer.
