TRNA-guanine15 transglycosylase (EC 2.4.2.48, tRNA transglycosylase, transfer ribonucleate glycosyltransferase, tRNA guanine15 transglycosidase, TGT, transfer ribonucleic acid guanine15 transglycosylase) is an enzyme with systematic name tRNA-guanine15:7-cyano-7-carbaguanine tRNA-D-ribosyltransferase. [1] This enzyme catalyses the following chemical reaction

guanine 15 in tRNA + 7-cyano-7-carbaguanine 7-cyano-7-carbaguanine15 in tRNA + guanine

Archaeal tRNAs contain the modified nucleoside archaeosine at position 15.

Guanylyl transferases are enzymes that transfer a guanosine mono phosphate group, usually from GTP to another molecule, releasing pyrophosphate. Many eukaryotic guanylyl transferases are capping enzymes that catalyze the formation of the 5' cap in the co-transcriptional modification of messenger RNA. Because the 5' end of the RNA molecule ends in a phosphate group, the bond formed between the RNA and the GTP molecule is an unusual 5'-5' triphosphate linkage, instead of the 3'-5' linkages between the other nucleotides that form an RNA strand. In capping enzymes, a highly conserved lysine residue serves as the catalytic residue that forms a covalent enzyme-GMP complex.
