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.

D004926 Escherichia coli A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
