- |
? |
2.4.2.64 | guanine34 in tRNA + queuine |
the enzyme is responsible for the formation of queuosine in the anticodon loop (position 34) of tRNAAsp, tRNAAsn, tRNAHis, and tRNATyr |
Mus musculus |

2.4.2.64 | guanine34 in tRNA + queuine |
human tyrosyl tRNA Tyr. The eukaryotic tRNA-guanine transglycosylase enzyme inserts queuine into tRNA via a sequential bi-bi mechanism |
Homo sapiens |

2.4.2.64 | guanine34 in tRNA + queuine |
in the absence of queuine, this enzyme catalyzes an exchange between free guanine with guanine |
Oryctolagus cuniculus |
queuine34 in tRNA + guanine |
- |
? |
2.4.2.64 | guanine34 in tRNA + queuine |
the affinity of the rat liver tRNA-guanine transglycosylase for queuine is much greater than that for 7-(aminomethyl)-7-deazaguanine and guanine |
Rattus norvegicus |
queuine34 in tRNA + guanine |
- |
? |
2.4.2.64 | guanine34 in tRNA + queuine |
the enzyme replaces a guanine in the anticodon of tRNAs for Asn, Asp, His, and Tyr. In the absence of queuine, this enzyme catalyzes an exchange between free guanine with guanine |
