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. [1] [2] This enzyme catalyses the following chemical reaction

L- glutamine + 7-cyano-7-carbaguanine15 in tRNA + H2O L- glutamate + archaeine15 in tRNA

In Euryarchaeota the reaction is catalysed by ArcS.
