title: [Structure and protein composition of the bacteriophage T2L connector].
abstract: Methods of isolating structural bacteriophage T2 fragments containing: 1. a fragment consisting of a connector, tail tube and contracted sheath; 2. a fragment consisting of a free head, a connector and contracted sheath; 3. a fraction of some free tail tube and some free connectors; 4. a fraction of some free tail, free connectors and free fibers. The following parameters of connector consisting from a neck and a sleeve, which in its turn consists of a cap and a leg, are determined by means of electrone microscopy: 1) the length and the diameter of a cap and a sleeve being 45 and 145 A respectively; 2) the length and the diameter of a sleeve leg being 45 and 85 A respectively; 3) the length and the diameter of a connector neck being 85 and 70 A respectively. Polyacrylamide gel electrophoresis revealed in connectors proteins having molecular weight of 14 000, 15 000, 26 000 and 35 000 daltons.
