Definition
The chemical reactions and pathways involved in the biosynthesis of archaeosine, an archaea-specific modified base found at position 15 in the D-loop of certain archaeal tRNAs. Source: GOC:hjd, PMID:20129918
Comment
Archaeosine (7-formamidino-7-deazaguanosine) is a structural variant of the hypermodified nucleoside 7-deazaguanosine. The biosynthesis pathway starts with archaeosine tRNA-guanine transglycosylase (ArcTGT) which catalyzes the exchange of guanine at position 15 in the D-loop of archaeal tRNAs with a free 7-cyano-7-deazaguanine.
