title: Methionine dependence of virus-infected cells.
abstract: Mouse embryo cells nonproductively infected with human cytomegalovirus differed from noninfected cells by the impaired ability to grow in the medium containing homocysteine instead of methionine. Virus infection of mouse embryo cells grown in both kinds of media resulted in the increase of protein synthesis. In the infected cells grown on homocysteine this increase was followed by a quick decrease. The effects of homocysteine substitution could be abolished by the addition of low amounts of methionine (0.1 mM). Methionine uptake in the infected cells grown on homocysteine for 48 h was significantly higher than that in the noninfected cells.
