archaeosine	A 7-deazaguanine ribonucleoside having 7-formamidino-7-deazaguanine as the nucleobase. It is found in the majority of archaeal tRNAs specifically at position 15 of the dihydrouridine loop (D-loop), a position not modified in either eukaryotic or bacterial tRNA.	archaeosine
nucleoside oq	A 7-deazaguanine ribonucleoside obtained by formal epoxidation of the cyclohexene moiety of queuosine.	epoxyqueuosine
nucleoside q	A nucleoside found in tRNA that has an additional cyclopentenyl ring added via an NH group to the methyl group of 7-methyl-7-deazaguanosine. The cyclopentenyl ring may carry other substituents.	queuosine
