| The effects of polyamines on the activities of elongation factors EF-1 and EF-2, phenylalanyl-tRNA synthetase, and tRNA were investigated. The activities of EF-1 and EF-2 were mostly stimulated by spermidine among three kinds of polyamines. The activities of EF-1 and EF-2 were investigated in the presence of spermidine by 230 and 181%, respectively. The activity of phenylalanyl-tRNA synthetase was slightly increased in the presence of polyamines. The effect of spermine on the synthetase was higher than that of the other polyamines. The tRNA activity in the presence fo polyamines was increased by 206% with spermidine, by 144% with spermine, and by 114% with putrescine. According to these results, it is concluded that polyamines in higher plants stimulate the protein biosynthesis by promoting the activities of elongation factors EF-1 and EF-2, aminoacyl-tRNA synthetases, and tRNAs, but the effects of polyamines on the various components for protein biosynthesis are different in according to the kind of polyamines. |
