Iron atom per core effect on FT dynamics.

a. Mineralization rate over time as a function of iron APC. a series of simulations were run for which the initial ferritin concentration was 2.32×10-6M and iron added was 1.09×10−3 M, corresponding to 470 iron atoms per cage, while the initial iron content (APC) varied from 0 to 4300 (as indicated by the colorbar on the right). b. Core accumulation over time as a function of initial APC. From the same simulations that generated the plots in A, here the total core mineralization is plotted over time with the same variation in iron per cage of 0 to 4300 atoms. c. Maximum mineralization rate. Plotted is the maximum value for the mineralization rate as a function of iron atoms per cage. This is the maximum value from the curve in a over the entire time course. d. Time to sequestration and time to maximum mineralization rate. Plotted is the time taken to reach the maximum value for the mineralization rate shown in c. Also plotted is the time taken for 99% of the LIP in solution to be sequestered dependent on initial iron atoms per cage. For values over 3729 atoms per cage it took longer than the 25 second time course.
