Nucleotide in monomeric actin regulates the reactivity of the thiol groups.

It was shown that the thiol-shielding activity and the protective capacity of a nucleotide are interrelated with its binding capability to monomeric actin.

The effect of glutaraldehyde and phalloidin on the conformation of F-actin.

In the present study, it is shown that glutaraldehyde — and phalloidin — induced modifications of F-actin decrease the flexibility of thin filaments.

The detection of denervation-induced structural changes in actin by phalloidin.

It has been shown earlier, that actin from denervated muscles is not readily polymerized and does not actively combine with heavy meromyosin, so it was of interest to use phalloidin which binds specifically to F-actin affects these bonds to study changes in the actin structure occurring during denervation.
