“…We, however, tentatively named the enzyme D-threonine dehydrogenase, because we found the enzyme by using D-threonine. D-Threonine and D-threo-3-phenylserine are synthetic compounds and have not been found in the free form in nature, although the toxic peptide phalloidine contains D-threonine (30). The true physiological substrate of this enzyme is not yet clear.…”

“…lethal for rats (Wieland, 1957) but causes a strong, temporary inhibition of RNA polymerase II of liver nuclei (L. Fiume, F. Novello & F. Stirpe, unpublished work). oc-Amanitin given in this way did not affect the activity of RNA polymerase II of nuclei isolated from rat brain ( Table 2).…”
