Neisseria gonorrhoeae is unable to grow with sulfate but can use thiosulfate as sole source of sulfur. Thiosulfate sulfur transferase (TST) (rhodanese) activity was present in the cytoplasmic soluble fraction. In the same extract, thiosulfate reductase (TSR), trithionate reductase and tetrathionate reductase activities were also detected using hydrogen as electron donor in the presence of viologen dyes and hydrogenase from Desulfovibrio gigas . The significance of and the possible relationship between these different activities are discussed.
