Figure 4. Changing ferritin C4 channel variants L165I and H169F had no effect on biomineral formation (480 Fe2+/cage).

Figure 4

Amino acid substitution at the 4-fold ferritin cage axes had no effect on biomineral formation (A350 nm, (Fe3+O)x species). The absorbance maximum for L165I, H169F and WT was measured with rapid mixing, UV-vis spectroscopy and shown here for a set of representative curves (1 out of 2 independent analyses for each mutant).
