COMMENTARY 
LITERATURE
malfunction
metabolism
-
sulfur globule oxidation is strictly dependent on the dissimilatory sulfite reductase (DSR). The DSR system is dispensable in environments with sufficiently high sulfide concentrations
physiological function
malfunction
-
dissimilatory sulfite reductase mutants incapable of complete substrate oxidation oxidize sulfide and thiosulfate about twice as fast as the wild type, while having only slightly lower growth rates (70-80% of wild type)
malfunction
-
enzyme downregulation causes severe adaptive reactions of primary and secondary metabolism. Seedlings with 14% transcript levels compared with the wild type are early seedling lethal, while seedlings having 44% transcript levels are viable but strongly retarded in growth. Enzyme downregulation result in a higher sensitivity toward cadmium (2.6fold)
physiological function
-
the enzyme catalyzes the terminal step in the reduction of sulfate to sulfide
physiological function
-
optimal enzyme activity is essential for normal development growth
