the fraction of amino-acyl-trna synthetases bound to the detergent-insoluble cytoskeletal framework obtained after extraction of nrk cells by 0.1 % triton x-100 was estimated , by activity measurements , to about 80 % for phenylalanyl-trna synthetase and 40 % for the high-molecular-weight ( hmw ) complex containing the seven aminoacyl-trna synthetases specific for glutamic acid , isoleucine , leucine , methionine , glutamine , lysine , and arginine .
