Alternative tertiary structure of tRNA for recognition by a posttranscriptional modification enzyme.
R.Ishitani, O.Nureki, N.Nameki, N.Okada, S.Nishimura, S.Yokoyama.
Transfer RNA (tRNA) canonically has the clover-leaf secondary structure with the acceptor, D, anticodon, and T arms, which are folded into the L-shaped tertiary structure. To strengthen the L form, posttranscriptional modifications occur on nucleotides buried within the core, but the modification enzymes are paradoxically inaccessible to them in the L form. In this study, we determined the crystal structure of tRNA bound with archaeosine tRNA-guanine transglycosylase, which modifies G15 of the D arm in the core. The bound tRNA assumes an alternative conformation ("lambda form") drastically different from the L form. All of the D-arm secondary base pairs and the canonical tertiary interactions are disrupted. Furthermore, a helical structure is reorganized, while the rest of the D arm is single stranded and protruded. Consequently, the enzyme precisely locates the exposed G15 in the active site, by counting the nucleotide number from G1 to G15 in the lambda form.

Figure 1. A tRNA Modification Enzyme, ArcTGT, Replaces the Base at Position 15 in the D Loop, which Is Deeply Buried in the Canonical L Form of tRNA(A) The secondary and tertiary structures of tRNA in the canonical L form. The acceptor, D, anticodon, and T arms, and the variable loop are colored red, yellow, green, purple, and sky blue, respectively. The secondary structure is shown in the clover-leaf (left) and L-shape (center) diagrams. The RNA backbones are shown with thick lines, while the Watson-Crick base pairs are indicated with short thin lines. In the tertiary structure (right), the RNA backbone is shown as a tube model and the Watson-Crick base pairs are shown with sticks. The ArcTGT target site, G15, which is buried deeply in the tRNA tertiary structure, is circled.(B) Biosynthetic pathway of archaeosine. The guanine moiety of G15 is replaced with preQ[0] by the transglycosylation catalyzed by ArcTGT. Afterwards, the preQ[0] at position 15 is further modified to archaeosine on the polynucleotide chain, by an unknown pathway (Watanabe et al., 1997). The biosynthetic pathway of preQ[0] is also unknown.

Figure 2. Overall Structure of the P. horikoshii ArcTGT·tRNA^Val Complex(A) Stereo view of the ArcTGT·tRNA^Val complex. ArcTGT and tRNA are shown as ribbon models. The catalytic domain and the C-terminal domains of the ArcTGT subunit A are colored green and brown, while those of subunit B are colored deep blue and purple, respectively. tRNA-I and -II are colored sky blue and pink, respectively.(B and C) Close-ups of the ArcTGT-tRNA interaction interfaces. (B) The anticodon arm and the DV helix are accommodated into the cleft formed between the catalytic and C-terminal domains. (C) U8 to U17 of the protruded D arm are recognized by the C-terminal domains of subunit A and the catalytic domain of subunit B, and G15 is accommodated into the catalytic pocket. The coloring schemes of (B) and (C) are the same as in (A).(D) Schematic diagram of the ArcTGT-tRNA interactions.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
