d-Cysteine formation rates at different pH values. a, plot showing the d-cysteine formation rates at the pH values shown. Each point was calculated from a time course slope using four points for up to 30 days. For certain samples, where the correlation coefficient (R²) is not listed, only two time points were used. b, table of the calculated d-cysteine formation rates and their correlation coefficients (R²). Values are in units of % d-cysteine/day. For conditions, see “Experimental Procedures.”
