Transfer RNA (tRNA) is structurally unique among nucleic acids in harboring an astonishing
diversity of post-transcriptionally modified nucleoside. Two of the most radically modified …

RNA encoding the B subunit of the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid
(AMPA) subtype of ionotropic glutamate receptor (GluR-B) undergoes a posttranscriptional …

Information is still quite limited concerning the structural requirements in tRNA molecules for
their post-transcriptional maturation by base and ribose modification enzymes. To address …

tRNA‐guanine transglycosylases (TGT) are enzymes involved in the modification of the
anticodon of tRNAs specific for Asn, Asp, His and Tyr, leading to the replacement of guanine …

tRNAs possess a high content of modified nucleosides, which display an incredible
structural variety. These modified nucleosides are conserved in their sequence and have …

We present two different representations of the genetic map of Escherichia coli K-12, the
linkage map of known genes and other functional sites (Fig. 1; p. 1717) and the physical …

The eukaryotic tRNA-guanine transglycosylase (TGT) has been reported to exist as a
heterodimer, in contrast to the homodimeric eubacterial TGT. While ubiquitin-specific …

tRNA guanine transglycosylase (TGT) enzymes are responsible for the formation of
queuosine in the anticodon loop (position 34) of tRNA Asp, tRNA Asn, tRNA His, and tRNA …

Queuosine is a hypermodified nucleoside found in position 34, the anticodon wobble
position, of four tRNA species. This modification is distributed with near uniformity across all …
