The interpretation of the experimental data suggests that trypsin might induce conformational changes in the membrane structure which prevent or delay the first step of interaction between phalloidin and the membrane surface.

The structure of F-actin is stabilized to such an extent that it will be resistant to the depolymerizing action of 0.6M KI and of deoxyribonuclease I, to denaturation by heat (70 °° C), and to local ruptures caused by ultrasonication or by cytochalasin B.

Structural effects and functional implications of phalloidin and jasplakinolide binding to actin filaments
- Chemistry, Biology
It is shown in atomic detail that phalloidin, a mushroom toxin that is routinely used to stabilize and label actin filaments, suspends the structural changes in actin, likely influencing its interaction with actin binding proteins.

The enantioselective synthesis of the key amino acid (2S,4R)-4,5-dihydroxy-leucine is reported as a basis for the first total synthesis of phalloidin, which was accomplished by two different synthesis strategies.

It can be concluded that [3H]desmethylphalloin and most probably also phalloidine are not metabolized in the livers of rats and mice.

Stability of the “aqueous” conformation in a lipophilic environment is apparently the second prerequisite for a toxic action of phallopeptides.

The activation of myosin ATPase by act in-tropomyosin-troponin is reduced after tryptic digestion of actin- Troponin, which affects, according to SDS gel electro phoresis, mainly two components of troponin with molecular weights of about 32 000 and 25 000, respectively.
