title: Role of the gene 17 protein of bacteriophage T4.
abstract: Head-related particles of bacteriophage T4 were examined by using heat leakage scanning calorimetry. The 17- particles showed two endothermic peaks on thermograms during their thermal transition process, while 49- particles gave only a single sharp endothermic peak. Thermograms of 17- particles treated with 23- defective lysate were different from those of nontreated 17- particles, and closely resembled thermograms of 49- particles. The 31- defective lysate was also capable of converting thermal properties of 17- particles. These results suggest that there is a structural difference between 17- particles and 49- particles, and that the product gene 17 of bacteriophage T4 is involved in the structural conversion of prohead to a more completed structure.
