Abstract

The biochemical basis for the proline requirement of Chinese hamster ovary cells has been investigated. The results indicate an absence of conversion of glutamate to proline and a 90% reduction in ornithine transaminase, the first enzyme in the pathway converting ornithine to proline. Possible explanations for this double defect are discussed.
