Regulation of Bacteriodes fragilis katB mRNA by oxidative stress and carbon limitation.

abstract：:It has been previously established that Thiobacillus neapolitanus fixes CO2 by using a form I ribulose bisphosphate carboxylase/oxygenase (RuBisCO), that much of the enzyme is sequestered into carboxysomes, and that the genes for the enzyme, cbbL and cbbS, are part of a putative carboxysome operon. In the present stud...
