FIG. 5.
Effects of metabolites on whole-cell fluorescence. (A) Effects of acetaldehyde on the xylose-dependent increase in fluorescence (time course); (B) effects of metabolites on the xylose-dependent increase in fluorescence. The values in panel B are percentages of the xylose-dependent increase in the fluorescence of whole cells observed in the presence of both xylose and the additive indicated. Note that a decrease in xylose-dependent fluorescence is interpreted as a decrease in the NAD(P)H level and a decrease in the NAD(P)H/NAD(P)+ ratio.
