The developmental pattern of homologous and heterologous tRNA methylation in rat brain differential effect of spermidine.

Neurochemical research

Salas CE, Cummins CJ, Sellinger OZ.

Neurochem Res. 1976 Aug;1(4):369-84. doi: 10.1007/BF00966229.

UsingS-adenosyl-L-[Me-(14)C] methionine, rat cerebral cortex methyltransferase activity was determined during the early postnatal period in the absence of addedEscherichia coli tRNA and in its presence. [Me-(14)C] tRNA was purified from both systems and its [Me-(14)C] base composition determined. The...

Methylated nucleosides in tRNA and tRNA methyltransferases.

PMID: 24904644
Front Genet. 2014 May 23;5:144. doi: 10.3389/fgene.2014.00144. eCollection 2014.

To date, more than 90 modified nucleosides have been found in tRNA and the biosynthetic pathways of the majority of tRNA modifications include a methylation step(s). Recent studies of the biosynthetic pathways have demonstrated that the availability of methyl...

Multi-Substrate Specificity and the Evolutionary Basis for Interdependence in tRNA Editing and Methylation Enzymes.

Frontiers in genetics

Dixit S, Henderson JC, Alfonzo JD.
PMID: 30838029
Front Genet. 2019 Feb 14;10:104. doi: 10.3389/fgene.2019.00104. eCollection 2019.

Among tRNA modification enzymes there is a correlation between specificity for multiple tRNA substrates and heteromultimerization. In general, enzymes that modify a conserved residue in different tRNA sequences adopt a heterodimeric structure. Presumably, such changes in the oligomeric state...
