Fig. 1From: Developing a single strain for in vitro salvage synthesis of NAD+ at high temperatures and its potential for bioconversionIn vitro NAD+ salvage synthesis pathway. a In vitro pathway for NAD+ salvage synthesis (upper scheme) and for the ATP regeneration (lower scheme) are illustrated. Chemical substances are shown in the box (NAM, nicotinamide; NA, nicotinic acid; R5P, ribose-5-phosphate; PRPP, phosphoribosyl pyrophosphate; NaMN, nicotinic acid mononucleotide; NaAD, nicotinic acid adenine dinucleotide). b Gene name, function, and source of organism are summarized. The number of the gene is corresponding to the number in aBack to article page
