Abstract
PR4 is a lipid-containing bacteriophage which is able to replicate in Escherichia coli. The virus was labeled with either [14C]leucine and [14C]threonine or H235SO4 and then purified by several rounds of sucrose gradient centrifugation. Autoradiographs showed the virus to be composed of six major protein species with molecular weights (1) 68 000, (2) 47 500, (3) 38 500, (4) 35 000, (5) 20 700, (6) 16 500 daltons. Electropherograms showed protein No. 2 to be the major protein, comprising about 43% of the total weight of viral protein.This publication has 3 references indexed in Scilit:
