IUBMB Comments

Certain prokaryotic and eukaryotic tRNAs contain the modified base queuine at position 34. In eukaryotes and a small number of prokaryotes queuine is salvaged and incorporated into tRNA directly via a base-exchange reaction, replacing guanine. cf. EC 2.4.2.29, tRNA-guanosine34 preQ1 transglycosylase.

The expected taxonomic range for this enzyme is: Eukaryota, Bacteria

Synonyms
qtrt2, qtrtd1, queuine trna-ribosyltransferase 1, more
