Table 2. Equations used to evaluate 16S rRNA, rpsL and rplL chain elongation rates (see table 4 and tables S1 and S2).

Equation	Label in the text
ε rrs = (n*c-rrs/n*tr(rrs) • l p-rrs • μ	(6)
ε aa(i) = (n*c-rrs/n*tr(i)) • (n c-p(i)/R/n R(i)/tr(i)) • l aa(i) • μ	(13)
n R(i)/tr(i) = (α+3l aa(i))/2β	(18)
n R(i)(av) = l aa(i) n R(av) n c-p(i)/R (μ/ε aa(av))	(10#)

Equation (6) was used to evaluate ε _rrs; equations (13) and (18) were used to evaluate ε _aa(i); equations (18) and (10#) were used to evaluate n*_tr(i) for all ribosomal proteins of E.coli (μ = 0.42 h⁻¹) cited in Tables S1 and S2.

Equation (10#) is readily derived by rearranging equation (10).
