Abstract
Extremely high levels of paramagnetic manganese (Mn/sup 2 +/) which quench phosphorescent reactions have been found to inhibit the formation of thymine-containing dimers in M. radiodurans. Lowering the concentration of Mn/sup 2 +/ in the culture medium resulted in a lower intracellular concentration of Mn/sup 2 +/, an increase in the uv-sensitivity of this bacterium, and a larger photochemical yield of thymine-containing dimers. High levels of paramagnetic Mn/sup 2 +/ were not found in other test organisms which are more sensitive to uv-irradiation. One interpretation of this data is that in Micrococcus radiodurans Mn2/sup +/+ may bind to the chromosome and thereby reduce the photochemical yield of thymine-containing dimers.
