Sulfur Starvation, Sulfide Supplementation, and cysM Transcription in Campylobacter jejuni Strains with a Single Nucleotide Polymorphism.

The amino acid cysteine is essential to Campylobacter jejuni survival, providing the bacterial cells with the element sulfur. When cysteine is not available for uptake, C. jejuni can synthesize cysteine from serine and sulfide or thiosulfate. The cys…
