TRNA-guanine15 transglycosylase

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

guanine15 in tRNA + 7-cyano-7-carbaguanine 7-cyano-7-carbaguanine15 in tRNA + guanine
