vitK3 increases smeV mRNA levels. smeV mRNA levels were measured by real-time RT-PCR in the presence of vitK3 in the wild-type D457 strain and in the MBS287 strain, which overexpresses smeVWX. The data show that expression of smeV is induced by vitK3. Fold changes were estimated with respect to the value given by strain D457 in the absence of vitK3. Error bars indicate standard deviations of the results from three independent experiments.
