Figure 5From: ABC transporter FtsABCD of Streptococcus pyogenes mediates uptake of ferric ferrichromeComplementation of the ftsB mutant. Plasmid pCMVftsB carrying the ftsB gene was introduced into the ftsB mutant strain to obtain ftsB/pCMVftsB. The uptake experiment was performed exactly as in Fig. 3. Presented are the mean values ± SD of 55Fe3+ radioactivity associated with the bacteria.Back to article page
