Amino acid residues of the Escherichia coli tRNA(m5U54)methyltransferase (TrmA) critical for stability, covalent binding of tRNA and enzymatic activity (2007)

Urbonavicius, Jaunius, Jäger, Gunilla, Björk, Glenn R.

The Escherichia coli trmA gene encodes the tRNA(m5U54)methyltransferase, which catalyses the formation of m5U54 in tRNA. During the synthesis of m5U54, a covalent 62-kDa TrmA-tRNA intermediate is...

Identification of a novel gene encoding a flavin-dependent tRNA:m5U methyltransferase in bacteria--evolutionary implications (2005)

Urbonavicius, Jaunius, Skouloubris, Stéphane, Myllykallio, Hannu, Grosjean, Henri

Formation of 5-methyluridine (ribothymidine) at position 54 of the T-psi loop of tRNA is catalyzed by site-specific tRNA methyltransferases (tRNA:m5U-54 MTase). In all Eukarya and many Gram-negative...

Transfer RNA modifications that alter +1 frameshifting in general fail to affect -1 frameshifting (2003)

URBONAVICIUS, JAUNIUS, STAHL, GUILLAUME, DURAND, JÉRÔME M.B., BEN SALEM, SAMIA N., QIAN, QIANG, FARABAUGH, PHILIP J., ...

Using mutants (tgt, mnmA(asuE, trmU), mnmE(trmE), miaA, miaB, miaE, truA(hisT), truB) of either Escherichia coli or Salmonella enterica serovar Typhimurium and the trm5 mutant of Saccharomyces...
