title: Correlation between spermine stimulation of rat liver Ile-tRNA formation and structural change of the acceptor stem by spermine.
abstract: We have recently reported that the interaction of spermine with the acceptor and anticodon stems may be important for spermine stimulation of rat liver Ile-tRNA formation [Peng, Z. et al. (1990) Arch. Biochem. Biophys. 279, 138-145]. To pinpoint which interaction of spermine is more important for spermine stimulation of Ile-tRNA formation, Ile-tRNA formation and ribonuclease V1 sensitivity of tRNA(Ile) were studied using purified tRNAs(Ile) from rat liver, wheat germ, brewer's yeast, torula yeast and Escherichia coli. The results indicate that spermine stimulation of rat liver Ile-tRNA formation correlated with the structural change of the acceptor stem by spermine. The nucleotide sequence of wheat germ tRNA(Ile) was also determined.
