The slowly acting amatoxins bind to the DNA dependent nucleoplas-
mic RNA polymerase B (II) which is responsible for the
transscription of m-RNA. This enables one to discriminate between
form Band polymerase A (I), the enzyme catalyzing r-RNA synthesis,
and to recognize all bio- logical events depending on m-RNA
synthesis (protein synthesis after hormonal stimulation, growth of
certain virus species etc.). Also with the amatoxins is the
affinity for the receptor dependent on the conformation, visible by
ORD and CD. All of the toxic derivatives are inhibitory, whereas
not all of the inhibitory ones are toxic. This descrepancy is, in
part, resolved by the observation of nontoxic "amanullins"
dissociating more than ten times fast er from the enzyme than toxic
ones. The quickly acting phallotoxins bind to a protein closely
associated with the cytoplasmic membrane of the liver cell so
causing the formation of microfilaments, the nature of which as
actin has been proven by deco- ration with heavy meromyosin.
Accordingly phallotoxins also bind to muscle actin which in
presence of ADP and Mg++ immediately polym- erizes to a phallotoxin
containing F -actin (Ph-actin). Ph-actin is also formed from F
-actin by re action with phallotoxins. It differs from F -actin by
its resistance against 0.6 M KI. Responsible for its toxic
properties is the conformation of the molecule as can be followed
by ORD and CD spectroscopy and the presence of a special methyl and
hydroxyl group.
