Figure 2. Growth of D. radiodurans wild type and mutant strains.

The growth of DR_146T mutant (∆DR_146T, black) and SlpA mutant (∆DR_2577, purple) were much slower than that of the wild type (DRWT, blue), while the growth of the mutant deficient in the DUF490 motif of DR_146T (∆DR_146T-DUF490, green) was only slightly slower than that of the wild type. Cell growth was monitored by measuring the OD₆₀₀ of cell cultures.
