Sulfite reduction in mycobacteria.
Mycobacterium tuberculosis places an enormous burden on the welfare of humanity. Its ability to grow and its pathogenicity are linked to sulfur metabolism, which is considered a fertile area for the development of antibiotics, particularly because many of the sulfur acquisition steps in the bacterium are not found in the host. Sulfite reduction is one such mycobacterium-specific step and is the...
متن کاملOxidation and reduction of sulfite by chloroplasts and formation of sulfite addition compounds.
After exposing intact chloroplasts isolated from spinach (Spinacia oleracea L. cv Yates) and capable of photoreducing CO(2) at high rates to different concentrations of radioactive sulfite in the light or in the dark, (35)SO(2) and H(2) (35)S were removed from the acidified suspensions in a stream of nitrogen. Remaining activity could be fractionated into sulfate, organic sulfides, and sulfite ...
متن کاملCharacterization of anaerobic sulfite reduction by Salmonella typhimurium and purification of the anaerobically induced sulfite reductase.
Mutants of Salmonella typhimurium that lack the biosynthetic sulfite reductase (cysI and cysJ mutants) retain the ability to reduce sulfite for growth under anaerobic conditions (E. L. Barrett and G. W. Chang, J. Gen. Microbiol., 115:513-516, 1979). Here we report studies of sulfite reduction by a cysI mutant of S. typhimurium and purification of the associated anaerobic sulfite reductase. Sulf...
متن کاملAssimilatory reduction of sulfate and sulfite by methanogenic bacteria.
A variety of sulfur-containing compounds were investigated for use as medium reductants and sulfur sources for growth of four methanogenic bacteria. Sulfide (1 to 2 mM) served all methanogens investigated well. Methanococcus thermolithotrophicus and Methanobacterium thermoautotrophicum Marburg and delta H grew well with S0, SO3(2-), or thiosulfate as the sole sulfur source. Only Methanococcus t...
متن کاملYeast sulfate-reducing system. I. Reduction of sulfate to sulfite.
X35-APS-This substrate was synthesized from S%ulfur trioxide-pyridine complex and AMP by a method similar to that of Baddiley et al. (13) except for simplifications and modifications necessary for introduction of label. An alternat,ive method has been described by Reichard and Ringertz (14). Approximately 3.7 me of S35-HzS04 was dried at 80” in a reaction tube fitted with a ball joint and side ...
