A modified nucleotide on the 3'-side of the anticodon loop of tRNA is one of the most important structure element regulating codon-anticodone interaction on the ribosome owing to the stacking interaction with the stack of codon-anticodon bases. The presence and identity (pyrimidine, purine or modified purine) of this nucleotide has an essential influence on(More)
It has been shown that endoribonuclease activity of alpha-RNP particles and 26S proteasomes are changed under the action of inductors of programmed cell death. Treatment of K562 cells with inductors of apoptosis--doxorubicin (adriamycin) and diethylmaleate--lead to a significant stimulation of RNAse activity of alpha-RNP and to reduction of proteasome RNase(More)
The modified nucleotide 3′ of the tRNA anticodon is an important structural element that regulates the codon-anticodon interaction in the ribosome by stacking with codon-anticodon bases. The presence and identity (pyrimidine, purine, or modified purine) of this nucleotide significantly affects the energy of stacking in the A and P sites of the ribosome.(More)
