Nucleotide sequences of two glutamine tRNAs from HeLa cells.

We reported previously that 4.5S RNAj, is associated with poly A RNAs of rodent cells (1). However, this molecule was not found in human, monkey, cat, mink, rabbit or chicken cells ^1) . In HeLa cells, several 4S RNAs are released from the poly A RNA fraction (1) . We determined the nudeotide sequence of one of the most abundant 4S RNA species in this fraction. Nudeotide sequence analysis was p...

Comparison of nucleotide sequences in HeLa cell mRNA and hnRNA.

Nearest neighbour analysis of nucleotides in vertebrate DNA has revealed a marked deficiency in the frequency of occurrence of the sequence CpGp. By use of the fingerprinting technique of Sanger et al. (1965) to characterise the nucleotide sequences of HeLa cell hnRNA after T1 RNAase digestion, we have shown that this deficiency also occurs in hnRNA and that it appears to be a general transcrip...

Role of Pseudouridine Formation by Deg1 for Functionality of Two Glutamine Isoacceptor tRNAs

Loss of Deg1/Pus3 and concomitant elimination of pseudouridine in tRNA at positions 38 and 39 (ψ38/39) was shown to specifically impair the function of tRNAGlnUUG under conditions of temperature-induced down-regulation of wobble uridine thiolation in budding yeast and is linked to intellectual disability in humans. To further characterize the differential importance of the frequent ψ38/39 modif...

Post-transcriptional regulation of the steady-state levels of mitochondrial tRNAs in HeLa cells.

In human mitochondrial DNA (mtDNA), the tRNA genes are located in three different transcription units that are transcribed at three different rates. To analyze the regulation of tRNA formation by the three transcription units, we have examined the steady-state levels and metabolic properties of the tRNAs of HeLa cell mitochondria. DNA excess hybridization experiments utilizing separated strands...

The nucleotide sequence of a glutamine tRNA from rat liver.

A glutamate tRNA from rat liver was purified. By means of post-labeling techniques, its nucleotide sequence was shown to be: pU-C-C-C-A-C-A-U-m1G-G-U-C-psi-A-G-C- G-G-D-D-A-G-G-A-U-U-C-C-U-G-G-psi-U-mcm5S2U-U-C-A-C-C-C-A-G-G-C-G- G-C-m5C-m5C-G-G-G-Tm-psi-C-G-A-C-U-C-C-C-G-G-U-G-U-G-G-G-A-A-C-C-AOH. The sequence is remarkably similar to that of tRNAGlu from Drosophila melanogaster. Only 10 out o...
