Donald I. Stimpson, Julyet Aksiyote-Benbasat, and Victor A. Bloomfield abstract: We have determined the effects of temperature, pH, and ionic strength on the kinetics of attachment of purified T4D heads and tails, with the aim of understanding some of the mechanistic details of this viral assembly reaction. To produce heads for the reaction, we used an osmotic shock resistant mutant deficient in tails and tail fibers (10"/18 “/19"/34"/36'/37 “); for tails, a 13"/23 “mutant was used. We conjecture that the mutation in gene 13 was necessary to prevent connectors from being attached to both heads and tails, thus blocking theirjoining. To follow the reaction, we used quasi-elastic light scattering (QLS)[Aksiyote-Benbasat, J., & Bloomfield, VA (1975) J. Mol. Biol. 95, 335-357], in effect measuring the decrease in average translational diffusion coefficient of theheads as tails are attached. The head and tail concentrations were in the range 6 X 1010 and 1.2 X 1011 particles/mL, respectively, corresponding to about (1 or 2) X 10~ 10 M. This extreme dilution, which is possible because of the high scattering power of the heads, slows down the very rapid bimolecular reaction to^ 2= 400 s. We were able to measure the QLS autocorrelation function once every 50 s.
