Figure 2From: MamX encoded by the mamXY operon is involved in control of magnetosome maturation in Magnetospirillum gryphiswaldense MSR-1Intracellular iron contents during culture of WT, ∆ mamX , and C mamX . The intracellular iron content was much lower for ∆mamX (0.20%) than for WT and CmamX (both 0.47%). **, The difference between WT and ∆mamX was statistically significant (P < 0.01, by t test).Back to article page
