During the design phase, our emphasis was on the engineering of metabolic pathways that augment intracellular levels of NADPH. Consequently, taking into account the de novo biosynthesis of NAD+ and the metabolic pathway for NADPH production, we have incorporated the NadM, NADK, and PntAB proteins into the genetically engineered bacteria. This strategic introduction is aimed at facilitating the biosynthesis of NADPH while concurrently mitigating any disruptive effects on the bacteria's physiological functions.
