Engineering alanine dehydrogenase to favor nicotinamide cytosine dinucleotide for formate-driven alanine synthesis.
To bypass the availability limitation and metabolic crosstalk associated with native reduced nicotinamide adenine dinucleotide (NADH) pools in L-alanine production, a non-natural cofactor system may offer a compelling strategy to secure independent reducing power. Here, we engineered an alanine dehydrogenase (AlaDH) fr...
