Structural basis of the sulphate starvation response in E. coli: crystal structure and mutational analysis of the cofactor-binding domain of the Cbl transcriptional regulator.

Abstract excerpt

Cbl is a member of the large family of LysR-type transcriptional regulators (LTTRs) common in bacteria and found also in Archaea and algal chloroplasts. The function of Cbl is required in Escherichia coli for expression of sulphate starvation-inducible (ssi) genes, associated with the biosynthesis of cysteine from organic sulphur sources (sulphonates). Here, we report the crystal structure of the cofactor-binding...
