NADPH
-
presence of NADPH increases the sulfur reduction activity, but NADPH alone cannot be used as electron donor
-
no quinione, but enzyme complex contains cytochrome c and has two additional cytochromes, probably of b-type

-
additional information
-
all organisms except Spirillum sp. require an external hydrogenase for assay
-
additional information
