Western blot and densitometry analysis of XrvB protein abundance. Total protein was extracted from Xoc wild-type cells expressing XrvB protein fused with 3 × Flag cultured in XOM2 and NB medium. Data are presented as means ± SD (n = 3). The mean value of XrvB protein levels in bacterial cells cultured in XOM2 at OD₆₀₀ of 0.3 was set equal to 1. Significance was determined by Student's t-test. **P < 0.01
