Fluorescence resonance energy transfer between sites in G-actin. The spatial relationship between Cys-10, Tyr-69, Cys-374, the high-affinity metal and the nucleotide

Barden et al. (1987) studied this question. Fluorescence resonance energy transfer spectroscopy was evaluated on Spatial relationship between labels attached to residues in G-actin. Fluorescence resonance energy transfer spectroscopy determined the distances between various residues and binding sites in G-actin, ranging from 1.1 nm to 3.6 nm.
