Enzyme Information

tRNA-guanine(15) transglycosylase.
based on mapping to UniProt O58843
Guanine(15) in tRNA + 7-cyano-7-carbaguanine = 7-cyano-7-carbaguanine(15) in tRNA + guanine.
-!- Archaeal tRNAs contain the modified nucleoside archaeosine at position 15. -!- This archaeal enzyme catalyzes the exchange of guanine at position 15 of tRNA with the base preQ(0), which is ultimately modified to form the nucleoside archaeosine (cf. EC 2.6.1.97).
