From: Acetol biosynthesis enables NADPH balance during nitrogen limitation in engineered Escherichia coli
Change in concentration of NAD+ and NADP+ during the transition from growth to nitrogen-limited phase in E. coli B4. The shaded light gray and dark gray areas represent the growth and nitrogen limitation phases, respectively. Orange circles, black squares, and blue triangles represent biomass, NAD+, and NADP+, respectively. The error bars denote the standard deviation in the measurements obtained from technical triplicate samples
