In studying bacteriophage T4--one of the basic models of molecular biology for several decades--there has come a Renaissance, and this virus is now actively used as object of structural biology. The structures of six proteins of the phage particle have recently been determined at atomic resolution by X-ray crystallography. Three-dimensional reconstruction of the infection device--one of the most complex multiprotein components--has been developed on the basis of cryo-electron microscopy images. The further study of bacteriophage T4 structure will allow a better understanding of the regulation of protein folding, assembly of biological structures, and also mechanisms of functioning of the complex biological molecular machines.
KEY WORDS: bacteriophage T4, baseplate, tail sheath, infection mechanisms, virus structure, protein structure, cryo-electron microscopy, X-ray analysis, 3D reconstruction
