An investigation of bacteriophage lambda, its protein ghosts and subunits.
The sedimentation coefficients and molecular weights of bacteriophage lambda and its ghost were determined as So(20,w) = 416 x 10(-13) second and M = 57 x 10(6) for the virus, and So(20,w) = 141 x 10(-13) second and M = 21 x 10(6) for the ghost. The protein portion of the virus consists of at least two distinct types of subunits, with molecular weights of 55,000 and 110,000, which differ markedly in their amino acid content.
