BACKGROUND: CysB is a tetrameric protein of identical subunits (M(r) =, 36,000) which controls the expression of genes associated with the, biosynthesis of cysteine in bacteria. CysB is both an activator and a, repressor of transcription whose activity is responsive to the inducer, N-acetylserine; thiosulphate and sulphide act as anti-inducers. CysB is a, member of the LysR family of prokaryotic transcriptional regulatory, proteins which share sequence similarities over approximately 280 residues, including a putative helix-turn-helix DNA-binding motif at their N, terminus. The aims of the present study were to explore further the, complex molecular biology and curious ligand binding properties of CysB, and to provide structural insights into the LysR family of proteins., RESULTS: The ...

== Function ==
 +
[https://www.uniprot.org/uniprot/CYSB_KLEPN CYSB_KLEPN] This protein is a positive regulator of gene expression for the cysteine regulon. The inducer for CysB is N-acetylserine. Thiosulfate and sulfide act as anti-inducers.
