- KmA and KmB are the Michaelis constants for NAD+ and nDNA, respectively. Ki is the dissociation constant for nDNA with unadenylylated DNA ligase (i.e. substrate inhibition constant for nDNA). Kia is the dissociation constant for NAD+ with unadenylylated DNA ligase. Kip is the dissocation constant for NMN. Kir is the dissociation constant for AMP. Standard errors of best-fit values are shown.
