Comments	p.2587 left column bottom paragraph:"A single ribosome chelates > 170 Mg2 + ions [ref 23], and a bacterial cell can contain up to 70,000 ribosome particles [ref 24] (Table 1). Assuming a cell volume of 1 μm^3[ref 25], the entire pool of 70,000 ribosomes chelates at least 12 mM Mg2 +, the equivalent of 25% of the total Mg2 + in the cytoplasm (Table 1 and Chart 1)."
