Structural and Kinetic Characterization of Hyperthermophilic NADH-Dependent Persulfide Reductase from Archaeoglobus fulgidus

Table 3

Specific activity of AfNpsr under anaerobic conditions at 70°C.

Substrate	Specific activity (min^-1)
NADH	NR^a
Cysteine persulfide
Glutathione persulfide
CoA persulfide
Polysulfide^b

^aNR: no reaction. ^bThe reaction was performed in 1 M Tris, as in (8).
