Translation of glutamate dehydrogenase mRNA in a reticulocyte cell-free system.

Messenger RNA template activity for glutamate dehydrogenase was detected in poly(A)-rich RNA extracted from rat liver polysomes. Enzyme synthesized in cell-free reticulocyte system was detected by measuring enzyme activity in the translation incubation mixture using dual wavelength spectrophotometric technique. The translation product was also identified by a partial purification of the labeled synthesized enzyme and by coelectrophoresis with the carrier enzyme preparation from mitochondrial matrix.
