LITERATURE
in presence of Tween 20. The enzyme has more than one disulfide bond and takes multiple forms depending on the extent of the reduction
-
native enzyme partially by preparation of thylakoid membranes, further purifications of the VDE by, i.e. anion exchange chromatography and gel filtration, lead to a significant loss of VDE activity
