Table I. Acetylation site stoichiometry in E. coli. The table summarizes stoichiometry measurements in the indicated experiments. WT = wild type, EP = exponential phase, SP = stationary phase, NAM = nicotinamide, knock out (Δ) strains are as indicated. Median stoichiometry, and the number and fraction of sites with greater than 1% and 10% stoichiometry are shown.
