From supramolecular vanadate receptors to enzyme models of vanadium Haloperoxidase [PDF]

, 2005
V-HPOs are enzymes catalyzing the halogenation of a variety of organic substrates using hydrogen peroxide and halide ions at slightly acidic condition[1-3]. The X-ray structure of V-HPO from Curvularia inaequalis[4, 5] reveals that the positively charged

Enzymes as Markers in Virus Preparations

Zeitschrift für Naturforschung B, 1972
Acid phosphatase and 5′-nucleotidase activity, present in fowl plague virus preparations, is separated from virus particles by a two-step sucrose gradient centrifugation. These enzymes may therefore be used to define the degree of purity of myxovirus preparations. ATPase activity, however, was found to be associated with virions of fowl plague.
