although both of the modified trnafmets showed larger km ( although to different extents ) and slightly smaller vmax than the intact trnafmet , they retained full activities of methylation with trna ( adenine-1- ) -methyltransferase ( m1a-methylase ) and of aminoacylation with aminoacyl-trna synthetase ( ars ) fraction as well , both of which were prepared from t. thermophilus strain hb 27 .
