Table 5(a).

Esq/hq for XDH; (a) protein components increasing the Esq/hq value in response to NAD+ binding in mV. Protein components that increase/decrease the Esq/hq difference by ≥ 20 mV are listed. For clarity, other residues are omitted from the table. For further information (side chain/backbone contributions), see Table S5 in Supporting Information.

Esq/hq(XDH) Esq/hq(XDH with NAD+) Difference a
NAD+ 358 358
Lys422 261 323 62
P (NAD+, proximal)b 36 36
Arg394 60 90 30
Lys343 90 114 24
a

Esq/hq(XDH with NAD+) − Esq/hq(XDH). A positive value here indicates an increased difference between Esq/hq in the two enzymes, while a negative value indicates a decreased difference.

b

A phosphate titratable site of the NAD+ diphosphate region proximal to the nicotinamide ring.
