Studies on a rat liver subcellular poly A-rich RNA fraction with glutamate dehydrogenase template activity
Abstract
A heterogeneous poly A-mRNA fraction was isolated from rat liver microsomes by phenol:chloroform extraction, millipore filtration, and poly U-agarose affinity chromatography. The fractions were characterized by their secondary structures and poly A contents. From translational studies, the isolated fraction was found to have high glutamate dehydrogenase template activity in cell-free systems containing microsomes or polysomes. A spectrophotometric procedure for following enzyme biosynthesis was also developed.
