Schematics of the unique tRNAs found in ARMAN-2 genome. (A) tRNAPro (CGG) possessing a D-arm with a single Watson–Crick base pair (boxed). This feature is also found in synonymous tRNAPro(UGG). (B) Pre-tRNACys (GCA) with an intron located at the non-canonical position 59/60 forming relaxed BHB motif (hBH type). (C) Pre-tRNAPro (GGG) with introns located at two adjacent positions (53/54 and 59/60) within the T-loop forming a strict BHB motif (hBHBh′ type). Intron sequences are indicated by gray text.
