| Abstract: | Aminoacyl-tRNA synthetases in Drosophila are present in large macromolecular aggregates having mol. wt in excess of 106 Daltons. After cellular fractionation these enzymes are found in the post-microsomal hard pellet, the post-microsomal soft pellet, and the post-microsomal supernatant fractions. The distribution of specific enzyme activities within these fractions varies and is dependent upon the specific tRNA synthetase being studied. |
