Journal ArticleDOI
A Study on the Motion Of Protenis in Excitable Membrane Fragment by Nanosecond Fluorescence Polarization Spectroscopy
TL;DR: It is concluded that proteins are strongly immobilized within the membrane phase within nanosecond fluorescence polarization spectroscopy.
Journal ArticleDOI
Fluorescence anisotropy of labeled F-actin: influence of divalent cations on the interaction between F-actin and myosin heads.
TL;DR: From these studies, one concludes that F-actin undergoes a conformation change by interacting with myosin heads, which depends on the nature of the divalent cations present in the solution.
Journal ArticleDOI
pH dependence of the fluorescence decay of tryptophan
Journal ArticleDOI
Study of actin and its interactions with heavy meromyosin and the regulatory proteins by the pulse fluorimetry in polarized light of a fluorescent probe attached to an actin cysteine.
TL;DR: The decay of anisotropy of the N-iodoacetyl-N'-(5-sulfo-1-naphthyl)-ethylenediamine fluorescence attached to cysteine-373 of actin can be characterized by two correlation times theta1 and theta2.
Journal ArticleDOI
Anisotropy decay of labelled actin. Evidence of the flexibility of the peptide chain in F-actin molecules.
TL;DR: The small value of the free F actin correlation time indicates that the protomer peptide chain is very flexible around its C terminus, probably involving the motion of a molecular lobe in the interaction of actin with myosin during the muscular contraction.
