title: Shutoff of histone synthesis by Mengovirus infection of Ehrlich ascites tumor cells.
abstract: The histone synthesizing capacity of mengovirus-infected Ehrlich ascites tumor cells and of their corresponding postnuclear supernatants was investigated as a funcion of time post-infection. In addition, histone synthesis was compared with the synthesis of other basic host proteins under identical conditions. In the scope of mengovirus infection of Ehrlich ascites tumor cells the less complex fraction comprising basic protein, separated from the acidic proteins by carboxymethyl cellulose chromatography, can be regarded as a representative of total host protein. Histones and the remaining basic host proteins therefore are well suited as easily identifiable indicators of the host protein synthesizing potential of mengovirus-infected Ehrlich ascites tumor cells. The cessation of histone synthesis proceeds faster than the arrest of the synthesis of other basic host protein.
