Abundance and usage of metal ions. (A) Simulated abundances of metal ions that bind on enzymes of cells under 116 conditions compared with measured metal ion contents of cells from various studies (Dataset S3). A single cell dry weight of 13 pg (26) was used to convert cell weight to cell count. (B) Proteins that account for high usage of each metal ion across the 116 simulated conditions.
