## Abstract The protein products of at least 21 phage genes are needed for the formation of the tail of bacteriophage T4. Cells infected with amber mutants defective in these genes are blocked in the assembly process. By characterizing the intermediate structures and unassembled proteins accumulati
## Abstract Bacteriophage T4 tail fibers are rodlike structures with a contour length of about 1400 Γ , a diameter of about 45 Γ , and a total mass of about 600,000 daltons. The assembly of the tail fibers and their subsequent attachment to the phage particle are under the control of 8 phageβinduced
## Abstract The characteristics of pure preparations of shortβtail fibers of bacteriophage T4 have been studied in the optical and electron microscope. Three main structures were observed: 1) spheres of 8.1 nm diameter; 2) fibers 43 nm long and 3.8 nm thick; and 3) fibers 54 nm long and 3.2 nm thic
## Abstract Mixtures of bacteriophage T4D particles with up to six tail fibres attached were seprated and analyzed in a quasielastic light scatteringβband electrophoresis apparatus. The electrophoretic mobilities and diffusion coefficients of the seprated bands were determined during the same exper
