Archaeosine synthase (EC 2.6.1.97, ArcS, TgtA2, MJ1022 (gene), glutamine:preQ0-tRNA amidinotransferase) is an enzyme with systematic name L-glutamine:7-cyano-7-carbaguanine aminotransferase. This enzyme catalyses the following chemical reaction
L-glutamine + 7-cyano-7-carbaguanine15 in tRNA + H2O
⇌
{\displaystyle \rightleftharpoons }
L-glutamate + archaeine15 in tRNA
In Euryarchaeota the reaction is catalysed by ArcS.
