additional information
?
-
-
the enzyme introduces corrosion of 316L stainless steel in the presence of NAD+. The enzyme induces the occurrence of cathodic and anodic microsites on the same electrode surface
-
-
?
H2 + NADP+
H+ + NADPH
-
the enzyme likely functions in the regeneration of NADPH and thus reuses the hydrogen produced by the membrane-bound hydrogenase in proton respiration
-
-
r
H2 + NADP+
H+ + NADPH
-
the hydrogen consumption activity is 1 order of magnitude higher than the hydrogen production activity
-
-
r
H2 + NADP+
H+ + NADPH
Solidesulfovibrio fructosivorans
-
heteromeric complex in which HndA and HndC constitute the NADP-reducing unit and HndD constitutes the hydrogenase unit
-
-
?
H2 + NADP+
H+ + NADPH
Solidesulfovibrio fructosivorans
-
biological function probably involves production of reduced pyridine nucleotides
-
-
?
H2 + NADP+
H+ + NADPH
-
in the presence of ferredoxin and a ferredoxin-NADP reductase
-
?
H2 + oxidized benzyl viologen
H+ + reduced benzyl viologen
-
-
-
r
H2 + oxidized methyl viologen
H+ + reduced methyl viologen
Solidesulfovibrio fructosivorans
-
reduction requires all four subunits, a form lacking HndD shows no activity towards methyl viologen
-
