Crystallization (Commentary)

Crystallization (Comment) Organism
in NAD(P)(+)-free, NAD(+)-bound, and NADP(+)-bound states. The nicotinamide of NAD+ stacks the isoalloxazine ring of FMN so that NADH can directly transfer hydride. The bound NADP+ also has a compact conformation but is bound in a reverse direction, which is not suitable for hydride transfer Sulfurisphaera tokodaii
